Château de Talmont was founded by the Count of Poitou in the 10th century and the first documentary records appear between 1040 and 1046. In 1138 the castle was held by Joscelin de Lezay, who was attacked by Louis VII; despite being considered invulnerable because it could be resupplied from the sea, the castle was burnt by the king. Talmont passed on to the Mauléons by the 1140s, but in 1182 Richard I of England became the lord of Talmont; he remained in control of the castle until his death in 1199, when it was returned to the Mauléon family.
The castle was enlarged during by the King Richard I of England with round towers, curtain wall and new gate. Most of the castle was demolished in the 17th century.
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.
