Bråborg was a former Royal castle at Bråviken. The house was built by Queen Dowager Gunilla Bielke in 1588-1590 and she lived there after her husband, King John III of Sweden, died in 1592. Gunilla Bielke herself died at Bråborg in 1597. Bråborg was later owned by her son, duke John of Östergötland. In 1612 he married his cousin, princess Maria Elisabeth of Sweden. They both died at Bråborg in 1618.
The building was partly destroyed in a fire in 1669, and in 1719 it was burnt down by a Russian army. The army also attacked the nearby town of Norrköping. The inhabitants needed stone to rebuild their town and used building material from the ruins of Bråborg. The new manor house at Bråborg was built about 1,000 metres from the burnt down house.
Today, a ruin is all that remains of the estate. The foundations and cellars are still visible today, together with the moats and parts of the gardens.
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.
