Broholm is a private estate and manor house, first mentioned in 1326 when owned by Absalon Jonsen Ulfeldt. From 1641, it was inherited by the Skeel and Sehested families for whom it was the seat from 1759 to 1930. The main wing with its round tower was built for Otte Skeel in 1644. In 1839, it was renovated in the Neo-Gothic style by Gustav Friedrich Hetsch. The corner tower was added in 1895 and the south wing in 1905. Substantial renovation and adaptation work was carried out in the 1920s and the 1950s. Part of the premises has now been converted into a hotel. There is also a museum of antiquities on the estate.
The Museum of North Antiquities is part of the manor and it has 10,000 antiquaries collected by Sehested, then (1881), owner of the manor. These antiquaries are a collection from an area of 5 miles (8.0 km) around the manor house. These finds are dated to the stone, bronze and iron ages. In addition, some gold ornaments were also found on the estate. Excavations revealed the Broholm gold hoard with an approximate weight of 4.15 kg. Deemed to be the biggest gold hoard of the country from the Migration Period, items include golden bracteates, as well as necklaces and pieces worn on the arm.
The estate is also famous for breeding of Broholmer dogs, of the St. Bernard Dog class of dogs with short hair with links to the pedigree of German Bulldog. These dogs are reported to be a common sight in the Copenhagen neighborhood. It is a national breed and the Copenhagen Kennel Club was charged with breeding them and establishing their pedigree. The Danish dog is also reported to be closely related to the English Mastiff. The better specimens are bred in the Broholm estate and hence given the name Broholmer Dogs.
References:The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
