The typical star shape of the 17th-century Swedish ramparts that once surrounded the Old Town can easily be spotted on a colour map as most of the pointy bits are now parks. The only intact section, complete with its moat, lies to the west of the centre. Where the rampart meets the western end of Kuninga, it’s pierced by this tunnel-like gate that once defended the main road which headed to the river-ferry crossing and on to Tallinn.
