Château d'Orcher was built to protect the mouth of the River Seine. The square keep was surrounded by a trapezoidal enceinte, defended in the 13th century by three square towers. In 1360 it was partly destroyed on the orders of officials from Harfleur. Rebuilt later, it was taken by the English in 1415 at the same time as Harfleur.
Thomas Planterose took possession of Château d'Orcher in 1735 and over the next ten years set about transforming the castle. He employed master masons François de la Motte and Jacques Lesueur, both from Picardy, and a master plasterer from Caudebec-en-Caux. The elegant woodwork was created by a carpenter Le Roux. The two north towers and the ruins of the great keep in the north-west were demolished, along with the curtain walls. In 1795, following the division of the estate with the death of Madame de Melmont, the property was described as a 'dwelling house castle and accessories and a farm of 145 acres'. In the 19th century, the estate became the property of the Rochechouart family, who had the castle, notably the tower, restored in 1857 by the architect P. Philippon.The castle grounds are open to the public all year. The Château d'Orcher is listed as a monument historique by the French Ministry of Culture. It also includes an imposing square crenellated tower.
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.
