Mali Tabor Castle was mentioned for the first time at the end of the 15th century. It was then owned by the Ratkay family but its builders are unknown to this day. Between 1490 and 1504 it was owned by the viceroy of Croatia-Hungary John Corvinus. For almost three centuries it was owned by the powerful Hungarian family of Rattkay (1524-1793). In 1972, Ivan Rattkay left the Mali Tabor castle to his nephew, the baron Joseph Wintershoffen, in whose possession it remained until 1818, when it was inherited by Rikard Jelačić from the Zaprešić branch. They owned it until 1876, and from then it was owned by the Irish baron Henry Cavanagh.
In the earliest phase of construction the castle had the shape of a rectangular building with defense walls and four semi-towers. The western wall, is probably the original defense wall of the old Mali Tabor castle.
During the second phase of construction the castle was transformed into a one-storied Baroque palace. It remained in this function until the 19th century. In 1861 a one-storied annex was built in the eastern wing of the castle on the northern side. This was also the time when the northern defense wall of the castle was torn down and a new entrance portal was built. The portal has been preserved to this day. The castle is abandoned for many years today. It is in a bad state and for sale.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
