Aren't these geomag tiles? Is it a model?

EDIT: There seems to be a book shelf in the background. So we're in the livingroom of someone who has built the miniature dome of a church or postmodern building. Shall we name the location of the livingroom or of the real building?
In the latter case I'd like to begin with Dome of St. Peter's Basilica in Rome.

EDIT2: proceeding with...
- Pantheon in Rome
- Hagia Sophia in Istambul
- Etchmiadzin Cathedral dome in Ejmiatsin, Armenia
- The Dome of the Rock in Jerusalem
- Great Mosque of Kairouan in Tunisia
- St. Mark's Basilica in Venice
- Shah Mosque, Iran
- Cathedral of the Annunciation, Moscow Kremlin
- ...

EDIT3: nice coincidence:
- Frederik's Church in Copenhagen (directly related to Amalienborg Palace, birthplace of Margarete II who happens to be central part of our current pictionary )
