The Old Synagogue in Dubrovnik is the oldest Sefardic synagogue still in use today in the world and the second oldest synagogue in Europe. It is said to have been established in 1352, but gained legal status in the city in 1408. Owned by the local Jewish community, the main floor still functions as a place of worship for Holy days and special occasions, but is now mainly a city museum which hosts numerous Jewish ritual items and centuries-old artifacts.
Located in one of the many tiny streets of the Old Town of Dubrovnik, it is connected to a neighboring building which has long been owned by the Tolentino family, who have been caretakers of the synagogue for centuries. The internal layout is different from other European synagogues and has gone numerous refurbishments throughout the centuries, and has a mixture of designs from different eras. The building has sustained damage several times, with the great earthquake in 1667, World War II, and the Croatian War of Independence in the 1990s. The damage has since been repaired as closely as possible to its original design.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
