Kreuzlingen Abbey was founded in about 1125 by Ulrich I of Dillingen, Bishop of Constance, as a house of Augustinian Canons. In 1144 Pope Lucius II, and in 1145 Emperor Frederick Barbarossa took the monastery under their protection. Kreuzlingen became an Imperial abbey. The abbots, now Imperial prelates, were territorial lords of the small lordship of Hirschlatt north of Friedrichshafen, and this was also their place of refuge in times of war.
The first monastery, as the result of the construction of the town wall intended to protect Stadelhofen from Appenzell, stood outside the suburb.
After the Swabian War, in the Peace of Basle of 15 October 1499 the Duke of Milan ceded the sovereignty of Thurgau to the Swiss. This so angered the inhabitants of Constance that they burned down the abbey of Kreuzlingen. The city was compelled to rebuild the abbey, and on 17 April 1509 Abbot Peter I von Babenberg (1498-1545) was able to rededicate the new church.
During the Thirty Years' War, despite the neutrality of the Swiss, an army entered Thurgau via Stein am Rhein, advanced on Kreuzlingen and besieged Constance unsuccessfully, losing several thousand men. When on 2 October the troops left Kreuzlingen, the people of Constance destroyed the abbey a second time. It was now decided that the monastery should not be rebuilt right up against the walls of Constance, but should be removed from it by not less than the distance of a cannon shot.
On 4 July 1650 the foundation stone of the new premises was laid and on 25 October 1653 the church of Saints Ulrich and Afra was dedicated.
It was constructed according to plans by Michael Beer of Vorarlberg, the founder of the Auer Zunft between 1650 and 1653, by the master builder of Constance, Stephan Gunertsreiner, and the mason Melchior Gruber. The Chapel of the Mount of Olives was constructed in 1760, and four years later the church and parts of the monastery were remodelled in the Rococo style.
The monastery was severely restricted from 1798 by the cantonal government, and despite considerable resourcefulness in developing new educational functions in order to remain in existence, was eventually dissolved in 1848 by the Canton of Thurgau. Some of the buildings, including the library wing and the Lady Chapel with the crypt, were demolished. The remaining buildings were designated for use by the canton's teacher training college. The church was preserved for the use of the town and is now a basilica minor.
In the early 1960s, the church was totally renovated. Shortly afterwards, on the night of 19-20 July 1963, as a result of welding work in the roof of the seminary, the entire building burnt down. The fire did not claim the external walls, the choir screen, the choir ceiling and the choir stalls, or the greater part of the wooden figures in the Chapel of the Mount of Olives. Thanks however to the enormous contributions of the conservator Albert Knoepfli and the deacon Alfons Gmür the church was rebuilt under the direction of Hans Burkard by 1967.
The ceiling paintings by Franz Ludwig Herrmann show scenes from the monastic life of Saint Augustine of Hippo. The magnificent choir screen was made in 1737 by Johann Jakob Hoffner. The statues, larger than life-size, of Saints Ulrich and Afra were carved by Hans Christoph Schenk. Of particular interest is the Chapel of the Mount of Olives with a crucifix and a Calvary. The ceiling painting shows Moses with the brazen serpent and is also by Franz Ludwig Herrmann (1761). The representation of the Mount of Olives, made out of beechwood by Innozenz Beck, contains about 250 original statuettes, about 30 centimetres high, carved of Swiss stone pine wood ('Arvenholz') in about 1720-1730 somewhere in the south-eastern Alpine region.References:
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
