The church of San Esteban was designed with a single nave covered with a pitched wooden roof and a semicircular apse topped with a half barrel vault.
Of particular interest are the decorative sculpted motifs, and especially those on the main doorway. This stands slightly in front of the façade and is protected by a gable supported on carved modillions. It has three semicircular archivolts decorated with a range of motifs (chessboard, serrated designs, studs, four-petalled flowers) standing on four columns –two each side– with capitals carved with floral motifs.
Highlights of the interior include the Triumphal Arch of the apse, conceived with double semicircular archivolt with a dust cover, supported on four historiated capitals, two of them with religious themes (the Crucifixion and the Evangelists), and two with chivalric scenes.
