Michakská, an alley at the northeast corner of Horní náměstí, the city's main square, leads to the treasure. Originally constructed in the 13th century, the current church by Giovanni Pietro Tencalla was done in 1676-1703.

The fairly plain exterior does not prepare one for the wonderful interior. Except for St. Nicholas Mala Strana in Prague, this was the finest Baroque interior I saw on my 35 day explorations of the region.
