This pair of picturesque, ivy-covered towers at the entrance to Viru Street is often the first glimpse visitors get of Old Town.
Anyone passing between them couldn't be blamed for thinking they've left the 21st century behind and landed smack in the middle of the 18th.
The towers are actually only the foregates of what was a much more complex gate system built in the 14th century. It included a large, square tower that stood father back along the street, close to where the city wall can be seen.
Most of the gate was pulled down in the 1880s to make room for traffic, but these two towers remained and have since become a symbol of the town.
