Buzza Tower is a prominent landmark on the hillside between Hugh Town and Old Town. It was originally built as a windmill in 1834 but was was restored in 1912, when the seating was added round the base, as a memorial of the visit by Edward VII to the Islands. The Camera Obscura was opened in 2014; it is sadly no longer operating.
