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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
