This cathedral is well worth a visit. The building in itself is beautiful and gives you an insight in the history of Brno. Do yourself a favour and buy a ticket to climb up the stairs of the tower. There is a small museum with some beautiful liturgical objects, but it is the view that takes away the top price. Spectacular. Mind you, there isn’t much space on both viewing platforms, but it certainly wasn’t busy when we visited.
