While visiting the famed London Bridge in Lake Havasu City yesterday I came across this mysterious looking door located beneath the bridge. While it is probably nothing more than a storage space or maybe a utility access point, it does evoke a feeling of darkness and intrigue. Iron bars on a steel door locked from the outside can have that effect.
