Church of San Miguel
The Church of San Miguel belonged to an old Capuchin convent, built in 1629, the date that appears on the coat of arms on its main facade. Inside, it houses the altarpiece of the Virgin of Pero. The building has a Latin cross plan, with a broad nave divided into three bays, a transept and a straight sanctuary. It is covered by barrel vaults with lunettes, except for the central bay of the transept, over which an elliptical half-vault rises with radial ribs and a plasterwork boss.
At the foot of the church stands a choir over a segmental arch, fitted with a rich Baroque wrought-iron balustrade centred by a radial half-sun bearing the letters AVM. The exterior walls are rendered, giving the building a sober and severe appearance. The main facade, whose current look is the result of a modern refurbishment, is especially notable. Above its lintelled doorway, set beneath a cushioned arch, there is a triglyph pedestal and a triangular pediment crowning the facade. Between the columns is a Mannerist coat of arms of the town, dated 1629.
Altarpiece of San Miguel
On the Gospel side is the altarpiece of San Miguel. This work, from the second half of the 18th century and in Rococo style, contains a carving of the saint from the same century and preserves its symmetrical side altarpiece.
Main altarpiece
In the presbytery stands the main altarpiece, which covers part of the front wall of the church. The polychromy of this mid-18th-century Baroque work, imitating coloured marbles, differs from its original appearance and must have been carried out in the late 18th or 19th century, at the same time as that of the side altarpieces. Except for the image of the Virgin of Miracles, which serves as the titular image, the other carvings are Baroque, contemporary with the altarpiece and of popular style. The side sections contain Saint Peter and Saint Paul, while the attic is presided over by a Calvary with Our Lady of Sorrows and Saint John, flanked by carvings of bishop saints, possibly Saint Saturnin and Saint Fermín.
Altarpiece of Saint Lucy
On the Epistle side is the altarpiece of Saint Lucy, which forms a pair with the side altarpiece of San Miguel, repeating its design and decoration. The central niche houses a dressed image of the saint, apparently an 18th-century work.
Altarpiece of the Virgin of Pero
Directly opposite this work is the altarpiece of the Virgin of Pero, which, judging by its style, dates from the early 18th century and may be linked to the workshops of Tudela. The altarpiece contains a carving of the Virgin, also from the 18th century. The work was donated in 1733 by Pedro Bustín. In this church there is also a Crucified Christ, larger than life-size, dating from the 17th century.
