The numerous Romanesque churches (most 12th century), many outside the walls, have simple basilican plans with single-cell or aisled naves, short presbyteries with semicircular apses and portals without tympana. Lively figured capitals on the apses of S Andrés and S Segundo were carved by Cantabrian sculptors influenced by S Martín, Frómista. Capitals and corbels at S Vicente, the nave of S Andrés and the apses of S Pedro bear a more limited repertory of animal and foliate motifs derived from Santiago de Compostela Cathedral and the western bays of S Isidoro, León.
