Glücksburg Castle is one of the most important Renaissance castles in northern Europe. It is the seat of the House of Schleswig-Holstein-Sonderburg-Glücksburg and was also used by the Danish kings. Situated on the Flensburg Fjord the castle is now a museum owned by a foundation, and is no longer inhabited by the ducal family.
The castle was built from 1582 to 1587 by Nikolaus Karie for John II, Duke of Schleswig-Holstein-Sonderburg, (1545-1622) at the site of an former monastery, the building material was partly reused in the castle. The grounds of the monastery were then flooded to create a large pond almost entirely surrounding the castle.
The castle is built on a 2.5 metres high granite foundation that emerges from the water. The bricks used for the construction were mainly taken from the demolished monastery. The base area is a square with sides of nearly 30 metres, consisting of three separate houses with their own roofs. While the great halls and the vestibule are situated in the middle house, the living space is in the two side houses. The chapel is the only room that is part of two houses.
The building had typical renaissance adornments, that were removed in the 19th century, otherwise the exterior has remained more or less unchanged for over 400 years.
The kitchen garden created in 1622 was the castles only garden until the eighteenth century, as the old monastery garden was lost with the construction of the pond, that was built as defence structure, but also used for fishing. Between 1706 and 1709 a small pleasure garden was created in the area of today's rose garden. From 1733 on, a baroque garden was laid out in the main park in front of the outer buildings, where an orangery was constructed in 1743.
In the twentieth century, the formal gardens were remodelled into English landscape parks, though the sections of the older garden remain. The orangery was renovated in 1827 into a neoclassic building, and is now used for art expositions and concerts.
The Glücksburger Rosarium was created in the area of the former castle nursery in 1990/91, and grows more than 500 different roses. In contrast to the castle gardens, it is a private garden and has an admission fee.References:
The Porta Nigra (Latin for black gate) is the largest Roman city gate north of the Alps. It is designated as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site. The name Porta Nigra originated in the Middle Ages due to the darkened colour of its stone; the original Roman name has not been preserved. Locals commonly refer to the Porta Nigra simply as Porta.
The Porta Nigra was built in grey sandstone between 186 and 200 AD. The original gate consisted of two four-storied towers, projecting as near semicircles on the outer side. A narrow courtyard separated the two gate openings on either side. For unknown reasons, however, the construction of the gate remained unfinished. For example, the stones at the northern (outer) side of the gate were never abraded, and the protruding stones would have made it impossible to install movable gates. Nonetheless, the gate was used for several centuries until the end of the Roman era in Trier.
In Roman times, the Porta Nigra was part of a system of four city gates, one of which stood at each side of the roughly rectangular Roman city. The Porta Nigra guarded the northern entry to the Roman city, while the Porta Alba (White Gate) was built in the east, the Porta Media (Middle Gate) in the south, and the Porta Inclyta (Famous Gate) in the west, next to the Roman bridge across the Moselle. The gates stood at the ends of the two main streets of the Roman Trier, one of which led north-south and the other east-west. Of these gates, only the Porta Nigra still exists today.
In the early Middle Ages the Roman city gates were no longer used for their original function and their stones were taken and reused for other buildings. Also iron and lead braces were broken out of the walls of the Porta Nigra for reuse. Traces of this destruction are still clearly visible on the north side of the gate.
After 1028, the Greek monk Simeon lived as a hermit in the ruins of the Porta Nigra. After his death (1035) and sanctification, the Simeonstift monastery was built next to the Porta Nigra to honor him. Saving it from further destruction, the Porta Nigra was transformed into a church: The inner court of the gate was roofed and intermediate ceilings were inserted. The two middle storeys of the former gate were converted into church naves: the upper storey being for the monks and the lower storey for the general public. The ground floor with the large gates was sealed, and a large outside staircase was constructed alongside the south side (the town side) of the gate, up to the lower storey of the church. A small staircase led further up to the upper storey. The church rooms were accessible through former windows of the western tower of the Porta Nigra that were enlarged to become entrance doors (still visible today). The top floor of the western tower was used as church tower, the eastern tower was leveled, and an apse added at its east side. An additional gate - the much smaller Simeon Gate - was built adjacent to the East side of the Porta Nigra and served as a city gate in medieval times.
In 1802 Napoleon Bonaparte dissolved the church in the Porta Nigra and the monastery beside it, along with the vast majority of Trier"s numerous churches and monasteries. On his visit to Trier in 1804, Napoleon ordered that the Porta Nigra be converted back to its Roman form. Only the apse was kept; but the eastern tower was not rebuilt to its original height. Local legend has it that Napoleon originally wanted to completely tear down the church, but locals convinced him that the church had actually been a Gaulish festival hall before being turned into a church. Another version of the story is that they told him about its Roman origins, persuading him to convert the gate back to its original form.
In 1986 the Porta Nigra was designated a World Heritage Site, along with other Roman monuments in Trier and its surroundings. The modern appearance of the Porta Nigra goes back almost unchanged to the reconstruction ordered by Napoleon. At the south side of the Porta Nigra, remains of Roman columns line the last 100 m of the street leading to the gate. Positioned where they had stood in Roman times, they give a slight impression of the aspect of the original Roman street that was lined with colonnades. The Porta Nigra, including the upper floors, is open to visitors.
