Dolmen de la Madeleine is an isolated dolmen located in a private field on the outskirts of the town of Gennes. It was probably built between 5 000-2 000 BC. There are a number of these sites in the area - but this one is said to be the largest. Like many of the larger dolmens, it has subsequently been re-used, in this case to house a bread oven. Although the bread oven is no longer in use as the dolmen is now a classified national monument, you can still see the remains of the oven.
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.
