Turkish district of Skopje, Macedonia - Ishak Bey Mosque was built in 1483 by Ishak Bey and it has a tomb behind it decorated with faience, and a Solomon’s seal made of dark and light blue tiles. It seems like a unique pattern (I never saw it before) which is composed from 48 small triangles that create a hexagram inside another hexagram. Picture is courtesy of Kat Rybnik from Flickr
