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.
