I took the following photos in Purley town centre (Croydon) in the rain. The clock tower is above a bakery and tea room called Munch. It's on the High Street (just off Brighton Road) and across the road from the public swimming pool.
The clocks are very close to Purley Cross Round About. Here is a link I posted earlier this year about the clocks at the roundabout.
