In spite of plenty of modernism and Renaissance architecture, the modestly sized provincial capital of Teruel glories principally in its Mudejar remains, the best in Spain [not even excluding Toledo!]. A website for the style generally in Teruel is to be found in the overview, and it's possible to access each of the four towers mentioned here if you scroll down that site.
First comes the Cathedral, though the tower is best seen from a bit farther away, as the mixture of styles in the building may not be considered wholly sympathetic. The feature of the Cathedral that could not excite a surfeit of admiration is the wonderful ceiling. It deserves all it gets.
The oldest of the towers is that of San Martín. It was being restored when I was there, but seen along the street from by the Ayuntamiento [Town Hall], it still looked pretty glorious. However, my favourite was one very like San Martín - that of El Salvador. Both these towers have very plain inner towers, but it’s only El Salvador that has steps between the two towers facilitating ascent. The view must be terrific. The street that passes under this tower runs steeply down from the Plaza de Torico and provides a stunning picture in the morning sun.
Lastly, we reach San Pedro. The website likens its tower to a smaller version of the Cathedral, but again, restoration work [the downside of out-of-season travel] made the exterior less than photogenic. However, more people are probably attracted to the inside anyway, because this leads to the mausoleum of the Amantes [Lovers] of Teruel. [See separate entry.] Perhaps I lack romance, but I was more impressed by the internal decoration of the church than by their alabaster tombs. Not a brick, not a pane of glass is missed – everything is ornate, and yet, instead of the brash horror that this would seem to convey, I found it strikingly beautiful.
