Built like a fortress after Alfonso IX took the city in the 13th century, the cathedral is topped by battlements and anchored by a tall square tower that could have been a defensive keep on its own. Inside, the basilica plan has three naves with late Gothic arches, a Renaissance choir stalls carved in walnut, and several Zurbarán paintings in the cathedral museum. The main entrance on Plaza de San Juan is crowned by a statue of John the Baptist.
The military appearance is a reminder that Badajoz spent most of its history as a contested frontier town. The cathedral museum, in the cloister, has the cathedral treasury and some excellent Flemish tapestries — worth the modest admission fee. The Plaza de San Juan around the cathedral, with its arcaded buildings and outdoor cafes, is the place to recover with a beer afterwards.
