Government Code & Cypher School (and a hidden message)

During World War I the British Army and Royal Navy both had separate intelligence agencies. Military Intelligence 1b, MI1(b) and Naval Intelligence Department 25, NID25, respectively. NID25 was initially known as Room 40, or 40 O.B., with O.B. referring to 'old building'. 

Following the conclusion of World War I the Cabinet's Secret Service Committee recommended that a peacetime codebreaking agency should be created. Lord Curzon, chairman of the Cabinet's Secret Service Committee, tasked Hugh Sinclair, Director of Naval Intelligence, with creating the new department.

Hugh Sinclair merged staff from NID25 with MI1(b), with the new agency consisting of between 25-30 officers, with roughly the same amount of clerical staff. Victor Forbes, of the Foreign Office, chose the cover-name 'Government Code & Cypher School (GC&CS).

The Government Code & Cypher School moved into Watergate House, Adelphi, with the Admiralty's Alastair Denniston, previously an NID25 officer, as its operational head. 

Its public directive was "to advise as to the security of codes and cyphers used by all Government departments and to assist in their provision". However, it also had a secret directive: "study the methods of cypher communications used by foreign powers".

Although officially formed on November 1, 1919, the Government Code & Cypher School produced its first decryption on October 19, 1919.

In 1921 the offices moved to the Broadway Buildings, opposite St James's Park, in the same building as the SIS, and came under the supervision of Hugh Sinclair. At the time Hugh Sinclair was Chief of SIS and Director of GC&CS.

On February 14, 2019, HM Queen Elizabeth II unveiled a City of Westminster plaque to mark the centenary of GCHQ.

However, keeping with the codebreaking, communications and cypher work of GCHQ, the plaque contains a hidden message, which most people don't even realise. 

Can you uncover the hidden message?

If you can't figure it out, there is a clue below. 

Various characters, on the plaque, have a dot or dash beneath them. 

If you find them all it reveals the message... 

Highlight the space between the quotation marks, below, to uncover the answer.

"1 HUNDRED YEARS"

So, did you work it out, or did you cheat?

Harold Stabler's Decorative Tiles on the London Underground

Hertfordshire.

Every station on the London Underground may appear to have a uniform style, internally, but, depending on when the station was built, it will have its own aesthetic. Exteriors, again, depend on the architect, the year it was opened and its location.

Baker Street, for instance, has tiles carrying the profile of Sherlock Holmes.

However, unique to five underground stations are relief tiles that are randomly placed, not all at eye level, depicting coats of arms, animals, buildings and even a portrait. The tiles are the same colour as the surrounding tiles, so as not to break up the uniformity of the style, but, once you spot them you can't stop looking for them.

Thomas Lord (1755-1832), English cricketer.

There are eighteen distinct tiles, spread across five underground stations. Although some have been repaired or replaced, the originals are easy to spot as they are usually marked with Stabler's signature 'S', somewhere on the tile.

Walking with Keilyn: Victory in Europe 80 Celebrations (VE-Day 80)

Monday May 5, 2025.

With the Victory in Europe 80th Celebrations getting  underway, today, Keilyn and I set off to enjoy the festivities. A taxi took us to Watford Underground station, where we boarded a Baker Street-bound train. My mum and uncle Martin had left earlier in the morning, heading for The Mall and St James's Park, in order to see the procession and catch the flypast from there. We changed at Finchley Road and caught a Jubilee line train, to Green Park, as Keilyn thought it would nice to catch up to mum and Martin. 

On exiting Green Park station we were herded, like cattle, down the east path towards The Mall. Vendors were selling Union flags and other merchandise, as the crowds flowed in both directions. On reaching The Mall we were given VE Day flags and then realised that there was no way we would see anything and, with my mum and Martin on the other side of the road, we retraced our steps, heading for Piccadilly.

Heading east, along Piccadilly, we made our way against the throng of people still heading to Green Park, before we reached Piccadilly Circus. To our surprise Piccadilly Circus was deserted of people, so we headed towards Leicester Square, stopping at Greggs to pick some nourishment, which we ate in an almost deserted Leicester Square. 

Once we had eaten we had our photos taken with Mr Bean and Paddington Bear, before heading along Irving Street and, after crossing Charing Cross Road, followed William IV Street to Strand. Again the roads were fairly clear, so we headed down Adam Street, where Keilyn had her photo taken outside the door of Number 10, before we turned down John Adam Street, heading for York Buildings.

At the end of York Buildings, on the left-hand side, is a lovely building which was the first home of GCHQ (Government Communications Headquarters). A green plaque, affixed to the wall, tells us this. However, if you look at the plaque closely, it contains a hidden message, that many people miss. Can you work it out?

We then entered Victoria Embankment Gardens, beside the York Watergate, and headed for Kippo's Coffee & Gelato, as I was in need of a coffee, while Keilyn was aching for a hot chocolate. With drinks in hand we walked along Victoria Embankment, before climbing the steps to Waterloo Bridge. Our vantage point from where we would watch the flypast.

As we still had time, we crossed the bridge and visited the National Theatre, checking out the view from its terraces and using the facilities. We then headed back up onto Waterloo Bridge, which was starting to fill up with people eager to see the flypast. We found a spot, almost in the centre of the bridge, and waited. I was glad that we had dressed for the weather, as the wind began to pick up and, off beyond Canary Wharf, we could see rain falling from the clouds. We all hoped that it would pass around us, which it did, fortunately. While we waited we took pleasure in waving at the tourists on the boats, passing below us, cheering when they waved back.

I had written a list of the order of the aeroplanes taking part in the flypast, which Keilyn read from as the BBMF Lancaster came into view. Then followed a Voyager and an A400m Atlas, a C-17 Globemaster III, a P-8 Poseidon with Two Typhoons, an RC-135 Rivet Joint with 2 F-35B Lightnings, the Red Arrows brought up the rear with 4 Typhoons.

The flypast took just over 5 minutes, but was really impressive to watch... and hear.

Marlborough Road (former) Underground Station

Marlborough Road (former) Underground station building.

If you travel on the Metropolitan line, between Finchley Road and Baker Street, you will pass through three closed stations. Although difficult to see and with much of the infrastructure now removed, they are Lord's, Swiss Cottage and Marlborough Road. The latter is the easiest to see and is used to evacuate the Metropolitan line, should the need arise.

Marlborough Road is in an open section of the line, which was built using the cut-and-cover method, with the station building still surviving.

Located at the junction of Finchley Road and Queen's Grove, Marlborough Road station opened on April 13, 1868 as part of the first northward extension, from Baker Street, of the Metropolitan Railway.

The Metropolitan began to suffer from passenger congestion, at its southern end, resulting in new deep-level tunnels being constructed between Baker Street's Bakerloo line tunnels and Finchley Road.

Walking with Erin: Baker Street to Soho Square... and beyond

Saturday May 3, 2025.

Today I was joined on my London trip by Erin, who wanted to visit Liberty London, to explore the entire shop.

So, we headed off by catching a taxi to Watford Underground station, where we boarded a train to Baker Street. I then gave Erin the choice of catching a Bakerloo line train to Oxford Circus, or we could walk there. Erin decided we should walk.

We crossed Marylebone Road and headed east to Park Crescent and onto Portland Place, Langham Place and then Regent Street. For a Saturday afternoon the pavements were quite empty, making our walk a little easier. At Oxford Circus we turned onto Argyll Street, where we stopped for lunch at Wok to Walk. Erin is fond of noodles.

Once we had eaten we continued along Argyll Street and entered Liberty London, with Erin heading straight for the makeup and perfume departments. Then it was down into the basement where more perfumes and scents could be found. Various testing strips were sprayed and then wafted beneath our noses, before we made our way up the stairs to the clothing departments.

Erin checked out some of the dresses and outfits, inspecting the designs and quality, obviously deciding which designs she could use in her own designs. Every floor was investigated. Books and stationery, housewares and linen, and everything in between. Then it was back to the ground floor and the small shop, where, even the sale items, had eye-watering prices.

We exited the shop onto Carnaby Street, where around thirty to forty mopeds, including Lambrettas and Vespas, were preparing to embark on a road trip. The Mods were all dressed in period clothing, from Parkas to Italian-cut suits, while the scooters were customised with foxtails and extra mirrors, with some supporting custom paint jobs. The noise was deafening, while the smell of petrol filled the small area. I decided it was best to move onto Great Marlborough Street, where the area was more spacious and would allow for a better vantage point. Sure enough all of the scooters made their way off Carnaby Street and, as soon as the traffic allowed, took off along the road. A short video of the scooters and their departure.

We then continued our walk along Great Marlborough Street, spotting a 1948 Cadillac, before continuing onto Noel Road, where we turned south along Berwick Street, spotting a street market ahead of us. One stall, in particular, that caught Erin's eye was 'Crochets by Amy', where hand-made crocheted items were for sale. After scanning the various items Erin decided that she wanted a small pink whale, which I purchased for her. After looking at a few more stalls, chatting with the friendly vendors, we ended up going back to 'Crochets by Amy', where Erin purchased a crochet duck.

We then turned along Peter Street and onto Meard Street, up Dean Street, along Bateman Street and onto Frith Street, finally reaching Soho Square, where we sat in the dappled shade to have drink and rest. This small square was filled with people enjoying the afternoon sun. Children were running around, while others were playing table tennis. Young people were lying on the grass, while others were sitting on the countless benches. It is a wonderful little oasis, with a faux Tudor building at its centre.

Suitably rested we made our way out of Soho Square along Sutton Row to Soho Place and across Charing Cross Road to Outernet Place. A massive screen affixed to the building advertised 'Kleenex x Mr Doodle!', so we headed inside, where we were confronted by a large glass box, made to look like a tissue box, with half a dozen people inside of it, busily cleaning the glass. Intriguing. After listening to some of the other visitors and talking with one of the security personnel we discovered that Mr Doodle had teamed up with Kleenex to promote their products, for one day only. Today!
