Dudhope Castle was originally built in the late 13th century by the Scrymgeour family. This was replaced around 1460.
James V visited in April 1540. The castle was further extended in 1580 for James Scrimgeour and Magdalen Livingstone to its current L-plan structure with additional circular 'angle' towers, although these were demolished in the 18th century.
During the centuries Dudhope Castle was held by four different families, of which the Scrymgeours held the post for some 370 years.
In 1795 the park and the grounds were leased to the Board of Ordnance, who used Dudhope as a barracks for 95 years, from 1796 to 1879. Additional buildings were constructed, including a hospital, officers quarters, stables and guard-rooms. The castle building itself was used as accommodation for 400 soldiers. The Board of Ordnance finally abandoned the castle in 1881.
The building was later occupied by the Ministry of Works and was used as a military barracks during both the 1914–18 war and the 1939–45 war. A time gun was formerly located in the grounds of the castle and fired daily at 1pm. It ceased to be used in 1916 so as not do disturb patients at the nearby Dundee Royal Infirmary who were suffering from shell-shock.
The castle passed to the corporation of Dundee who made an attempt to demolish the castle in 1958. In the years 1985 to 1988 the castle was redeveloped and is now in use as offices, a conference centre as well as housing the University of Abertay Dundee's Dundee Business School. During restoration, one of the main rooms was designated as the Scrimgeour room. It is furnished with wall hangings pertinent to the Scrimgeours and the drapes on the windows are made from material in the Scrimgeour tartan.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
