Oliwa Cathedral is dedicated to The Holy Trinity, Blessed Virgin Mary and St Bernard. The first Cistercian monastery on the site was founded by Sambor I of Gdánsk, Duke of Pomerania, in 1186. The first Romanesque oratory was burnt down in 1224 during the pagan Prussians crusade. It was rebuilt in 1234-1236, but destroyed again by Prussian crusade.
In 1350 fire that was caused by chimney soot excess completely consumed both the church and the monastery. The present shape of both of those buildings date back to the second half of the 14th century. During the rebellion of the city of Gdańsk the mercenary army attacked the monastery and burned it to the ground in 1577. The current church was rebuilt between 1578-1583 and inaugurated in 1594.
In 1831 Prussian authorities closed down the Cistercian monastery in Oliwa. The church, together with some of the buildings belonging to it, was handed over to a Catholic parish. It took until 1925, when under a papal bull issued, Pope Pius XI established the Diocese of Gdańsk and by that raised the Oliwa church to the dignity of a cathedral. Oliwa became the capital of the diocese and a seat of bishops.
Oliwa cathedral is a three-nave basilica with a transept and a multi sided closed presbytery, finished with an ambulatory. The façade is flanked by two slender towers, 46-metres tall each with sharply-edged helmets. It is enlivened by a Baroque portal from 1688, as well as three windows of different sizes and three cartouches. The crossing of the naves is overlooked by a bell tower, a typical element of the Cistercian architecture. The cathedral is 17.7m high, 19m wide and 107m long (97.6m of the interior itself), which makes it the longest Cistercian church in the world. It holds works of art in Renaissance, Baroque, Rococo and Classical style of great artistic value.
All the 23 altars of the cathedral are of great historical value. They are mainly Baroque and Rococo, partly made of marble. Their iconography depicts the main principles of the post-Trent church. Most outstanding are the present High Altar (1688), which is the most profound Baroque work of art in Pomerania; and the Netherland Renaissance style altar, which until 1688 played the role of the main one. The paintings in the altars, presbytery and main nave were made by the famous 17th- century artists: Herman Han (1574–1628), Adolf Boy (1612-1680), Andrzej Stech (1635–1697) and Andreas Schlütera (1660–1714). The interior also holds Rococo chapels of the Holy Cross and St John of Nepomuk, an ambo, tombstones, epitaphs, the Pomeranian Dukes tomb, the Kos family tomb, bishop’s crypt, antique chandeliers, canopies, and many other antiquities, including a feretory of great cultural value, showing Our Lady of Oliwa with an Infant Jesus. The feretory is always carried during the annual walking pilgrimage to the Calvary of Wejherowo. The archcathedral holds organ concerts all year round and the beautifully restored monastery (now belonging to Gdańsk Seminary) displays the collection of the Diocesan Museum. Oliwa Cathedral is very important place for the Kashubian culture.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.
