St Ia's Church, St Ives, is a parish church in the Church of England in St Ives, Cornwall. The church is dedicated to Ia the Virgin, also known as Ives, supposedly an Irish holy woman of the 5th or 6th century. The current building dates to the reign of King Henry V of England. It became a Church of England parish church in 1826. It was built between 1410 and 1434 as a chapel of ease: St Ives being within the parish of Lelant. The tower is of granite and of four stages (over 80 ft high): the church is large but not particularly high and built in a Devonian style rather than a Cornish one. An outer south aisle was added by the Trenwith family about 1500: this is now the Lady Chapel and contains a statue by Barbara Hepworth.
The font is of granite and most likely of the 15th century. It is carved with four angels holding shields. In the chancel, there are bench ends of the standard design and two other, complete benches. There is a brass to a member of the Trenwith family, 1463, and a monument to the Hitchens family by Garland & Fieldwick, 1815.
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.
