The Cathedral of the Blessed Virgin Mary in Truro was built between 1880 and 1910 to a Gothic Revival design by John Loughborough Pearson. It is one of only three cathedrals in the United Kingdom featuring three spires.
Truro was the first Anglican cathedral to be built on a new site in England since Salisbury Cathedral in 1220. It was built on the site of the 16th-century parish church of St Mary the Virgin, a building in the Perpendicular style with a spire 39 m tall. The central tower was finished by 1905 and the building was completed with the opening of the two western towers in 1910.
Pearson's design combines the Early English style with certain French characteristics, chiefly spires and rose windows.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
