Le Dolmen du Mont Ubé is a Neolithic / Chalcolithic () passage grave which was discovered in 1848 by workmen quarrying for stone. The passge leads into bottle shaped chamber that used to have four internal compartments each blocked with low stone slabs. The capstones were taken as well as all but one of the internal compartments. Within the passage stand three stones that may also have had a low sill at some time. These were later used to block of the passage so it could be used as a pigsty.Finds recovered from the workmens spoil heaps included 10 or 12 pots, a Jersey bowl, vase supports, flint and stone tools, stone axes, polished stone pendants and a grape cup (unique to the Channel Islands). Burnt and unburnt human remains were noted in the cists.
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.
