The Byzantine Bath in Thessaloniki is one of the few and best preserved of the Byzantine baths that have survived from the Byzantine period in Greece.
The baths date to the late 12th/early 13th century, and functioned continuously until 1940, when they shut down probably due to World War II and the German occupation of Greece. The Byzantine sources do not mention it, hence it is likely that it originally belonged to a monastery complex.
The bath's long use led to numerous alterations of the original structure over time. The original architecture follows the typical conventions of Roman baths. The original entrance in the south leads to the rectangular frigidarium rooms, which were used as dressing rooms. Then came two vaulted tepidarium rooms and finally two caldarium rooms. The latter were square in shape and featured hypocausts below the floor. One was covered by a dome supported by an octagonal base with eight windows, the other had a domed ceiling. To the north of the baths was the cistern that provided it with water, with a hearth beneath to warm it. In Byzantine times the building was alternately used by men and women, but in the Ottoman period the bath was divided into exclusively male and female sections, by blocking off each pair of rooms from each other.
The bath was one of several in the city, but is the only surviving in Thessaloniki and the largest and most complete of the handful of Byzantine baths surviving elsewhere in Greece.
In 1988, it was included among the Paleochristian and Byzantine monuments of Thessaloniki on the list of World Heritage Sites by UNESCO.
Following four years of restoration work, the bath was re-opened to the public as a museum and cultural space in June 2015.
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.
