[kéktúra] in yellow @ Pannonh-🍎
Somewhat off the blue tour - the kéktúra - on the yellow jerusalem pilgrimage route is the Pannonhalma Abbey with an impressive library. In the church there, some windows are made of thin light marble instead of glass, which lets in dull daylight.
The name of the abbey is like a play on words: Pannon-h-🍏 (alma = apple) So an Apple branch; -)
