The Basilica of Saint-Pierre-Aux-Nonnains is one of the oldest Christian churches in the world still standing. Erected sometime in the 4th century AD, it was originally part of a Roman-era spa when Divodurum, the former name of Metz, was a major military and trade center along the Germanic frontier. Specifically it was used as a pagan gymnasium when Christianity in Western Europe was still in its infancy. It was one of the few buildings in the city to remain standing after the Huns passed through in 451 AD.
Metz was an important cradle of Frankish civilization, with both Merovingians and Carolingians tracing their ancestry to the place. After the conversion of Clovis I to Catholicism, Metz became a Christian stronghold. During the 7th century, the old Roman gymnasium was converted to use as a Benedictine church. During the reign of Charlemagne, Metz was almost chosen as the capital city of the newly founded Holy Roman Empire, an honor which was instead bestowed on nearby Aachen. Neverthless Charlemagne was apparently fond of the old church, and two of his sons were buried in what would later be designated the Basilica of Saint-Pierre-Aux-Nonnains.
Amazingly, the original Roman structure remained essentially intact throughout the Middle Ages. Apparently by the 16th century the old edifice was showing its age, and the Church moved out. It then spent over 400 years in service as a warehouse: a perfectly intact thousand-year-old building, one of the best preserved Roman constructions in the world, was then used for storage. Thankfully, its historical importance was recognized in the 1970s and the basilica was restored. It is now used primarily as a concert hall, a fitting tribute to its medieval musical heritage.
The interior is much less Roman in appearance than the exterior, as the whole place was renovated in the 10th century, and again in the 20th century. Although still designated as a Basilica by the Roman Catholic Church, the building’s use nowadays is for musical functions and exhibitions. It is certainly an ideal place to see Gregorian Chant music performed.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
