Model of Old London Bridge, Church of St Magnus-the-Martyr

Inside St Magnus-the-Martyr Church, on Lower Thames Street, is a remarkable model of the Medieval London Bridge.

This four-metre long model was built by David T Aggett, a member of the Metropolitan Police. He was also a keen model maker and this model of Old London Bridge took him almost three years to complete.

The model shows how Old London Bridge would have looked in 1400 and is built, predominantly, from cardboard boxes. 

He was also a liveryman of the Worshipful Company of Plumbers, so he donated the model to the Church, which is the church of the Worshipful Company of Plumbers. 

As a little joke he placed a Metropolitan Policeman on the bridge, which people can seek to find when admiring the model. 

Besides the Policeman there are countless other figures going about their daily routines, which can bring a smile to your face.

St Magnus-the-Martyr Church was once the entrance way to the old London Bridge, before the bridge was demolished and moved 30 metres to the west. So, it is fitting that the model resides here.

Walking with friends: Barbican to Tower Bridge... and beyond

Thursday March 27, 2025.

Having celebrated my birthday, yesterday, I was eager to use my day off to visit London. With my girls at school I roped in my friend, Gary, to join me for the walk.

I took a bus to meet Gary at Rickmansworth station, where we caught a fast Aldgate-bound Metropolitan line train to Barbican. 

Our first stop was a visit to Postman's Park and the G.F. Watt's Memorial to Heroic Self-Sacrifice, which Gary had never seen, before we continued our walk south towards St Paul's Cathedral.

Turning on to Foster Lane I spotted the two open blue doors and, after climbing the three stone steps, we found ourselves in a secluded courtyard. This courtyard, once part of a graveyard, is a public garden that is owned by the church of St Vedast-alias-Foster.

A tree acts as a centrepiece to the slabbed and pebbled space, with various potted plants and shrubs dotted around the space. Two white walls are in juxtaposition with the brick walls, while the covered arcade adds an almost Mediterranean feel to this tranquil space. A framed display of Roman pavement pieces along with various plaques adorn the walls, while a relief sculpture of Canon Mortlock, by Jacob Epstein, is affixed to another wall.

But, I was here to see a rather obscure brick. It is a mud brick, etched with cuneiform writing, that was unearthed in Iraq and is almost 3,000 years old. Strangely, there is no plaque or marker, so I had to do some research on this piece of ancient history, on my return home.

Just metres from this 'secret' garden we saw a London Plane tree, growing in the grounds of the former St Peter West Cheap Church grounds. This platanus x acerifolia tree is said to be the oldest tree in the City of London.

From here we continued our route, by following Cannon Street, to Eastcheap, before turning down Pudding Lane, passing the Monument, before reaching Lower Thames Street, where we visited the Church of St Magnus-the-Martyr.

The Church of St Magnus-the-Martyr is a wonderful Grade I listed church, which was one of the first buildings to be destroyed by the Great Fire of 1666. Although this church dates from 1687, there has been a church here since the 11th century. 

Inside this church there is a model of the Old London Bridge, which was created by David T Aggett, a member of the Metropolitan Police who rose to the rank of Detective Superintendent in the Fraud Squad. He was also a keen model maker and this model of Old London Bridge took almost three years to complete. As he was also a liveryman of the Worshipful Company of Plumbers, he donated the model to St Magnus Church, which is the Plumbers' Company church. As a little joke he placed a Metropolitan Policeman on the bridge, which people can seek to find when admiring the model.

Having found the Policeman and some of the other interesting parts of the model we explored the rest of the building, before leaving the church and continued our walk along Lower Thames Street.

We stopped at Tower Hill Market for a bite to eat, which we ate on the square outside All Hallows by the Tower. The sun, by now, had burnt away the fog and mist, causing the temperature to soar, as we made our way across Tower Bridge to the south bank.

Pudding Lane Steps

These stairs lead to a viewing area looking out over the River Thames.

Exploring London, as I do, I invariably discover new shortcuts, pieces of history or some hidden gem that I knew nothing about.

So it was on this particular Bank Holiday as I, Keilyn and my friend Gary made our way from Aldgate, via a meandering route, towards Baker Street, taking in the sites along the way.

As we approached The Monument I remembered that there was a stairway that would lead to a viewing area, above the north bank of the River Thames, so we set about finding it.

The stairway was easy to find, being situated on the corner of Monument Street and Pudding Lane, so up it we climbed, with Keilyn going ahead and looking for fossils in the stone walls of the office building.

At the top of the stairway, with the offices to our right, we could look down on Pudding Lane on our left, while ahead was an information board and an engraved slab.

St Magnus-the-Martyr, City of London

Dedicated to St Magnus-the-Martyr, Earl of Orkney.

St Magnus the Martyr, London Bridge, is one of my favourite churches, within the City of London. It is an ornate church which has an almost Palladian style to it, with its white walls, Romanesque columns and gold relief. 

But, the highlight of the church for me, besides all of its long history, is the model of Old London Bridge, which shows how the bridge would have looked in the 1400s.
