Within the sturdy medieval walls of Romanos a rich history was played out on a large high plateau of the Alto Huerva region.
There, one of the best examples of Mudejar architecture, the tower of the church of San Pedro Apóstol, is found. The church was erected on the site of what was once an ancient castle, and two of its three cylindrical towers and the wall-walk remain intact.
The tower is some 30 meters high, could date to around 1400, based on its features, and was used as a watchtower, indicative of the town’s role in the Reconquest. Specifically, it is classified as a gate tower.
The interior is reached via the first floor, which reinforces the idea that it was used for defensive purposes. It is divided into superimposed rooms covered by pointed barrel vaults.
The abundant decoration on the tower is distinct in each of the sections into which it is divided. The exterior walls of the lowest section are almost entirely smooth, only decorated at the top with a row of angled bricks, zig-zags and checkerboard patterns. The second section features intertwined mixtilinear arches with knots at the top. On the west face of this second section is a projecting balcony, or machicolation, which breaks the decorative motif and emphasizes its defensive purpose. The third section is decorated with panels of interlacing figure eights, a Muslim decorative motif rarely used on Mudejar towers, but also present on the towers of Santa María in Calatayud and in Quinto.
The church adjacent to it was constructed of masonry with stone ashlars as reinforcement. The interior has a single nave with a polygonal apse and side chapels, and features altarpieces from the 16th, 17th and 18th centuries, the most striking of which is the main altarpiece, with its Renaissance design dedicated to Saint Peter.
Romanos also has a chapel devoted to Nuestra Señora de los Remedios, a Roman era fountain and several peirones, or wayside crosses: that of the Virgen del Pilar and that of San Antonio de Padua.
