Next to the entrance to Old Town Hall is Staromĕstské Podzemí. This is an underground tour of the dark and dusty history of Prague. While walking through a labyrinth of brick passageways, you will learn the origin of different structures – some dating back to the 12th century – and how they morphed over time. You will read the names of prisoners incarcerated underground. You will hear the chilling tales of how citizens died while defending against the Germans during the Prague Uprising in 1945.
