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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
