Built in the 15th century on the site of an earlier medieval fort, the Gothic Château de la Roche-Jagu was much larger originally. The one main wing left standing has severe good looks. There are few openings of any sort on the side dominating the river, reflecting its defensive role. However, a staggering line of 19 chimneys in a row adds a decorative flourish along the crest of the building. The façade on the other side is much lighter and more charming, with a fair number of windows, plus an eccentric tower perched up high.
The building has undergone major restoration work since the Côtes d’Armor county council took it over and began putting on events here. The grand hall on the ground floor was where functions were traditionally held; exhibitions today focus on themes to do with Côtes d’Armor, for instance the county’s hidden treasures, or its maritime riches. The grounds have been beautifully replanted, and awarded the status of Jardin Remarquable. A wonderful new terrace looks down on the dramatic, densely wooded banks of the Trieux from on high.
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.
