The Basilica of Notre-Dame de Boulogne is a minor basilica and a prominent landmark of the city. The first Christian building on the site was probably built by the Romans during the 4th or 5th century, on the peak of the hill that forms the modern haute ville.
According to legend, in about 633, while Saint Audomare (Saint Omer) was bishop of Thérouanne, an unmanned boat carrying a luminous statue of the Virgin Mary was sighted in the estuary at Boulogne. The statue was carried to the church and soon miracles were reported at the site. Between the 13th and 16th century the statue, known as Notre-Dame de la Mer ('Our Lady of the Sea') became a popular object of pilgrimage, bringing prosperity to the town.
In around 1100 a new church was built on the site and over the next few centuries underwent numerous changes, such as the addition of a choir in the 14th century. In 1308 it was the location of the wedding of Edward II of England to Isabella of France, an event commemorated by a memorial in the crypt.
In 1567, on the creation of the Diocese of Boulogne, the church was elevated to be its cathedral, and flourished until the French Revolution, when the Civil Constitution of the Clergy of 1790 brought it under government control. Worship in the cathedral was prohibited: the Convent of the Annonciades (Order of the Annunciation of the Blessed Virgin Mary) became the centre of worship in Boulogne, and after a period as a military warehouse, the cathedral was sold to traders from outside the city. The building was then demolished in stages, and, in 1793, the celebrated miraculous statue of Our Lady of the Sea was burned. Only a small portion of the statue's hand survived. Of the original cathedral, only the impressive Romanesque crypt from the medieval building survives.
Under the Concordat of 1801, which restored a reformed diocesan structure in France, the diocese of Boulogne ceased to exist. Its former territory was incorporated into the expanded Diocese of Arras.
A local priest and self-taught architect, Benoit Haffreingue, vowed to rebuild the destroyed cathedral to restore the honour of Our Lady of the Sea and return the episcopal seat to the city. After a vigorous campaign he was able to gain the support of many, including Victor Hugo and François-René de Chateaubriand, and soon had considerable public opinion behind him.
Construction of his design began in 1827 with the building of the rotunda and continued for nearly fifty years. The dome that now dominates the town was finished in 1854 and its western towers were completed in the 1870s. However, despite the support that Haffreingue's campaign gathered, the bishop's seat was not returned to Bologne and the building thus never regained its status as a cathedral. In 1879 the rebuilt church was declared a minor basilica.
Notre-Dame was built to a new design inspired by both Classical and Renaissance styles, and bears many similarities to St Paul's Cathedral. The area beneath the dome was initially designed to form the complete church, but additional funding allowed the expansion to the nave and transept that form a Latin cross. This gives the finished building the unusual internal appearance of being formed by two distinct churches.
The tall nave is dominated by its rows of slender Corinthian columns, with unusual features scattered throughout. Haffreingue's lack of professional training unfortunately gave the building an inherent fragility that led to the collapse of the nave's arches in 1921. During their reconstruction the whole building was reinforced with concrete, which without doubt allowed it to survive the bombing received by the city during World War II.
When Haffreingue began work on the new church in 1827, the workmen discovered a crypt that had lain unknown for centuries, having probably been filled in during the 1544 siege of Boulogne by Henry VIII of England. The crypt is 128 metres long in total, and is believed to be the longest in France. Its Romanesque columns date back to the 11th century
With 19th-century masonry accompanying the original medieval work, the many rooms also include the foundations of a Roman temple dedicated to Mars. Cannonballs from the siege of 1544 lie alongside offerings from the site's many medieval pilgrims.
The crypt includes a chapel in which the body of José de San Martín, the South American liberator, was buried between his death in 1850 and its return to Buenos Aires in 1861.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
