The Church of St Ambrose from the 13th century is a beautiful single-nave church with Romanesque-Gothic characteristics. It is located near the Upper City Gate where once the Benedictine Monastery of St Ambrose stood, whose original construction was mentioned as early as 941. The church got its present-day look when it was renovated in 1992.
The front side of the Church has characteristics of Romanesque architecture with a single entrance portal. Above the portal there is an opening in the form of a cross and above it a narrow Romanesque window.The single-nave area was vaulted by a semi-cylindrical ceiling of tufa (a variety of limestone), and from the interior side it is reinforced by two belts. The remains in its foundation bear witness that the church had a semi-circular apse. The present-day rectangular apse 5 x 4 metres in size was built later. In the 15th century the Church of St Ambrose was renovated and the church area widened. It obtained its present-day form by being renovated again in 1992. The church is used for celebrating the Mass, and because it is very acoustic, also for occasional concerts.References:
Goryōkaku (五稜郭) (literally, 'five-point fort') is a star fort in the Japanese city of Hakodate on the island of Hokkaido. The fortress was completed in 1866. It was the main fortress of the short-lived Republic of Ezo.
Goryōkaku was designed in 1855 by Takeda Ayasaburō and Jules Brunet. Their plans was based on the work of the French architect Vauban. The fortress was completed in 1866, two years before the collapse of the Tokugawa Shogunate. It is shaped like a five-pointed star. This allowed for greater numbers of gun emplacements on its walls than a traditional Japanese fortress, and reduced the number of blind spots where a cannon could not fire.
The fort was built by the Tokugawa shogunate to protect the Tsugaru Strait against a possible invasion by the Meiji government.
Goryōkaku is famous as the site of the last battle of the Boshin War.
