The Black Church dominates the medieval city center. It is an important and imposing structure. We ran into a bit of a problem with the guard in the church and the fact that some of the groups were slow to put away their cameras. Rich tapestries hang from the balconies, and Persian rugs are also on display. The pipe organ came from Prague and uses water pressure to create its unique sound. The area is only for pedestrian traffic, and the streets are lined with cobblestones. A shopping area is just off the square and has a beautiful fountain and a lovely clock tower.
