'Cantonal Tree' and 'Glockenspiel Clock', Swiss Court

The Glockenspiel Clock, Swiss Court.

If you approach Leicester Square, from the west, you will find yourself on Swiss Court. This small thoroughfare, less than 40 metres (130 feet) in length, was once home to the Swiss Centre.

The Swiss Centre, built between 1963 and 1966, was a 14-storey building that was a showcase for Switzerland and its products. The centre featured a commercial and trade centre.This included a branch of a Swiss bank and a Swissair ticket office tourist office. There was also a chocolate and souvenir shop, a cafe and, in its basement, several Swiss-themed restaurants.

The rest of the building was taken up with offices, residential spaces, a penthouse and a viewing gallery.

Astronomical Clock, Bracken House

It is always important to look everywhere, when walking around London. This includes looking up as well as down, as you navigate the labyrinth of London's streets, as you never know what you will see. 

This is how I saw what could be London's strangest clock.

It is quite easy to walk by the building at 10 Cannon Street, without paying it much heed. It is much like any other office block, built in the 1950s, rising nine-storeys into the sky, with larger windows than most buildings of the time. Its only real difference is the pink sandstone cladding. But, even this doesn't really make it stand out, standing as it does on its own.

But, above the door is something that should grab your attention. At first glance it looks like an enamelled tile, or an elaborate design to draw the eye. It is, in fact, a clock. But, not a boring old clock that just tells the time. This is an astronomical clock and it really is a wonderful object.

'Alunatime' by Laura Williams

'Alunatime', by Laura Williams, was launched on the Full Moon of October 22, 2010, and is the first, live 'real time' graphical notation of light and time.

It shows the lunar phases (wax and wane), the lunar day (rise and set) and tide cycles (ebb and flow). Governed by the relative position of the Earth, Moon and Sun, these fundamental rhythms have shaped our past and will continue to determine our future.

The Moon creates our tides and, with 70% of the Earth's surface covered in water, understanding the rising tides brought on by climate change, is becoming more important than ever.
