Within the houses the ceilings are often exquisitely carved and painted in Mauresque designs, such as are found in the Alhambra, and the tile-work for which Tetuan is known may be seen on floors, pillars and dados.
All lavatories, bath rooms, and water closets have dados of glazed brickwork.
Go through the main entrance to have a look at the entrance hall with its glazed tile dados.
