Nemuro Peninsula Chashi Sites is a grouping of twenty-four Ainu chashi on the Nemuro Peninsula in Nemuro, Hokkaidō, Japan that have been jointly designated a national Historic Site, out of a total of thirty-two chashi sites identified in the city. The grouping is also the first entry on the Japan Castle Foundation's 2006 list of Japan's Top 100 Castles.
Typically found at elevations of 5 metres to 50 metres above sea level, they are mostly situated on bluffs overlooking the Sea of Okhotsk, reinforced with U-shaped or semicircular moats. Relative to many of those elsewhere on the island, their state of preservation is good. They are thought to date from the sixteenth to the eighteenth centuries, and are associated with the 1789 Menashi–Kunashir rebellion.
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.
