Vladimir’s Golden Gate, part defensive tower, part triumphal arch, was modelled on a very similar structure in Kyiv. Originally built by Andrei Bogolyubsky to guard the western entrance to his city, it was later restored under Catherine the Great. You can climb the narrow stone staircase to check out the Military Museum inside. It’s a small exhibit, the centrepiece of which is a diorama of old Vladimir being ravaged by nomadic raiders in 1238 and 1293.
