Church of Santa María de Wamba Monument · Wamba, Montes Torozos, Valladolid Catholic church of Wamba (Montes Torozos), cruciform in plan with three naves and the chapels of Doña Urraca and the Osario, the latter decorated with human skulls and bones. Its oldest core, from the Mozarabic period, is attributed to Frunimio, a former bishop of León who around 928 refounded here a monastery dedicated to Santa María; the community disappears from the records between the 10th and 12th centuries, until in 1140 the infanta Sancha Raimúndez, sister of Alfonso VII, donated it to the Order of St John of Jerusalem, which undertook the late-Romanesque rebuilding of the 12th century. Its horseshoe arches, inherited from an earlier Visigothic monastery, make it one of the most singular churches in Castile. It was declared a historic-artistic monument in 1931.
