Beneath the streets of Windsor lies a time capsule, buried in 2011 and sealed for 50 years. Its contents encapsulate through images, information, and videos, what the town of Windsor was like in 2011. However, it’s not the capsule that captures the attention of passersby.

Fixed within the pavement is a working clock, ticking away under the feet of pedestrians. It was installed alongside the time capsule below, it sits within the same space as a previous pavement clock, originally installed in 1950. Sir Cyril Dyson, jeweler and clockmaker for the queen, sunk the clock into the pavement outside his shop as a showcase of his skills. The original clock went missing in the 1980s following the closure of Dyson’s store.

The pavement clock of Windsor is thought to be one of a kind in Britain, and those brave enough to level their ear to the timepiece have reported the distinct tick-tock of its mechanism emanating from below.
