Teruel Cathedral

For eight hundred years, this Mudéjar tower in Teruel, Spain, has stood in the heart of the town. But the base, a barrel vault that passers-by can walk through, dates all the way back to 1257. It was part of a monastery, not the church it is today. That came later, and it was Juzaff, a Moorish architect, who designed it. His Mudéjar reform, carried out in the second half of the 13th century, changed the monastery’s naves, giving them a new Gothic style. The Mudéjar tower was the result of this initial work. The construction of the Mudéjar tower was completed in 1257. The Octagonal roof lantern, a late addition, tops the square base, fronted by azulejos and ceramic glaze. Wander its square sides, trace the azulejos, and get a feel for a past that no longer exists.
