Situated on the banks of the River Adaja, San Segundo church was built in Caleno granite between 1130 and 1160. Before it was dedicated to St Segundo after the remains of the town's first Bishop were found in 1519, it had been dedicated to St Sebastian and St Lucia. The Bishop's remains were moved in 1615 with great pomp and ceremony to the chapel of St Segundo, which was built on to the apse of the Cathedral specifically as a final resting place.
The layout draws inspiration from the basilica style and has three naves and an upper end with three apses closed off with calotte and barrel vaults. Its slightly off-centre north-eastern orientation is probably due to the existence of an earlier church or an error made when the construction was being marked out. The southern porch has five archivolts set on columns and there are others of similar characteristics to the North and West, which were replaced in the 16th century. The structure of the naves was replaced in 1521 with a structure that shows Mudejar-style influences. Its current appearance is the result of refurbishment work that was carried out as from the 16th century.
The decoration with Romanesque sculptures is limited to a number of capitals with plant and figurative motifs. Inside, it boasts a sculpture of St Segundo in prayer by Juan de Juni.
There is a Roman altar stone opposite the west entrance that was found during recent archaeological work on the church.References:
Sweetheart Abbey was a Cistercian monastery, founded in 1275 by Dervorguilla of Galloway in memory of her husband John de Balliol. His embalmed heart, in a casket of ivory and silver, was buried alongside her when she died; the monks at the Abbey then renamed the Abbey in tribute to her. Their son, also John, became king of Scotland but his reign was tragic and short. The depredations suffered by the Abbey in subsequent periods, have caused both the graves to be lost. The abbey, built in deep-red, local sandstone, was founded as a daughter house to Dundrennan Abbey; this Novum Monasterium (New Monastery), became known as the New Abbey.
The immediate abbey precincts extended to 120,000 m2 and sections of the surrounding wall can still be seen today. The Cistercian order, also known as the White Monks because of the white habit, over which they wore a black scapular or apron, built many great abbeys after their establishment around 1100. Like many of their abbeys, the New Abbey's interests lay not only in prayer and contemplation but in the farming and commercial activity of the area, making it the centre of local life. The abbey ruins dominate the skyline today and one can only imagine how it and the monks would have dominated early medieval life as farmers, agriculturalists, horse and cattle breeders. Surrounded by rich and fertile grazing and arable land, they became increasingly expert and systematic in their farming and breeding methods. Like all Cistercian abbeys, they made their mark, not only on the religious life of the district but on the ways of local farmers and influenced agriculture in the surrounding areas.
The village which stands next to the ruins today, is now known as New Abbey. At the other end of the main street is Monksmill, a corn mill. Although the present buildings date from the late eighteenth century, there was an earlier mill built by and for the monks of the abbey which serviced the surrounding farms.
