• There’s a working drawbridge at the Tower of London, something not seen at the fortress since the 1970s. The bridge, which would have originally spanned a water-filled moat, was created in 1834 to allow munitions to be brought into the basement level of the White Tower from the wharf (the moat was drained in 1843 on the orders of the then-Constable, the Duke of Wellington). The bridge has been altered many times but the last time it was completely replaced was in 1915 while the tradition of raising it was carried on until the 1970s before it was permanently fixed in 1978. The new bridge draws on historic designs from 1914 and has been constructed of steel and English oak. It will be raised and lowered on “high days” and holidays and for educational purposes.
