Today it serves as a bridge between Old and New Town, and is also the hangout of choice for teenagers drinking super-strength lager. In summer tours of the interior are available, and well worth the look if you dont have an aversion to confined spaces. Interestingly, the moat that pins the Old Town in is another relatively recent addition to Warsaw. The original ditch was filled in back in the 18th century when the defences became obsolete, and the walls were incorporated into the dense tangle of townhouses that mushroomed up around. Fragments of these forgotten defences were unearthed in 1937, and a decade later, with Warsaw in ruins, architects took the decision to restore and expose these ancient walls.
