Box Hill Fort, Tadworth, Surrey
On Box Hill near Dorking several species of bats have taken up residence in Box Hill Fort, originally built as part of the plan to defend London from invasion at the end of the 19th century. It’s not an attractive looking fort by any means, built of reinforced concrete and never used, so it fell into disrepair but it is a scheduled Ancient Monument and will one day be fully restored. The bats live in the tunnels that were originally intended to store ammunition and because they’re protected by law, there’s no public access; instead, the curious are at liberty to wander round on the footpaths and see the exterior of the building. Box Hill Fort is an interesting part of the South East’s history all the same.
