Perhaps the most imposing structure in Prague's Old Town, Tyn is easy to spot, yet tricky to find the entrance for. But that adds to the charm, it's like a secret passage. Tyn stands out, like it's keeping an eye over the Old Town. A Gothic church with plenty of aesthetic character. I found my way inside and was struck by how lovely it is. Definitely take your time admiring the pieces and the atmosphere itself, everything within is worth your consideration. There is no entrance fee, but a small donation is requested, which I always provide. You can also buy post cards with professionally done photos of some aspects of the church. They are inexpensive and during my experience, they relied on the honor system.
