Schlosskirche Blieskastel

Mighty building, one reminds me strongly of Italian churches

The Castle Church (official name: Parish Church of St. Anne and St. Philip) is the parish church of the Catholic parish of St. Sebastian in Blieskastel, Saarpfalz district. It bears the patronage of St. Anne and the Apostle Philip and was built as a Franciscan monastery church in late Baroque and partly early Classical styles. The church is listed as an individual monument in the Saarland's list of historical monuments.

The castle church of Blieskastel is one of the most outstanding churches on the threshold between late Baroque and Neoclassicism in southwest Germany. It was built as a Franciscan monastery church from 1776 to 1781 according to plans by the architect and building director Peter Reheis under the Counts von der Leyen. Reheis worked under building director Friedrich Joachim Stengel in Saarbrücken until he was called to Blieskastel by Count Franz Karl von der Leyen in 1773. Since the dissolution of the convent in 1802, the church has served as a parish church dedicated to Saints Anne and Philip. It is a rectangular hall church with a recessed polygonal choir and a richly decorated gable façade. The gable roof is surmounted by a tower-like turret with an onion dome to the west and a smaller turret to the east. Extensive crypts lie beneath the choir and nave. The high-quality furnishings date from the time of its construction. Due to its prominent location above the town, the castle church occupies a special position in the urban fabric of the small Baroque residence of Blieskastel. The "large turret" is a characteristic landmark of Blieskastel due to its bizarre shape. From 2001 to 2004, the German Foundation for Monument Protection funded the restoration of the facade and the re-roofing of the Great Tower.
