You enter from Konviktska Street through a large gate which connects the back of the Bethlehem Chapel with a wall that has vines and flowers climbing up it. There's also an interesting overhead walkway connecting the two buildings, whose purpose is worth a moment's speculation. It looks like a tiny old wooden covered bridge. Maybe to allow clergy to move between buildings without having to slog through the churchyard? These buildings are definitely old enough to have had some gnarly mud around them, factor in a few chickens and no plumbing. Can't really see a priest wading in robes through a barnyard in galoshes... Anyway the passage is roughly second-story height, you could easily ride a horse underneath it.
This is all buried among the bent cobblestone streets in Prague's Old Town area. It's off the main path going between Old Town Square and the Charles Bridge, so you won't come across it en route to or from the most popular locations. Unless you're lost that is, which is what you really should be when you're in this area. You just don't go to prague to be where you know where you are, really.
Here's an art hint for all you statue-scavengers: go out the gate of Arkitekt, turn left, walk half a block, and look up.
