The exact date of the original Toulouse Cathedral is unknown; the first mention of a church building on that site is found in a charter of 844. In 1073 the bishop of Toulouse commenced work on a more elaborate structure, followed by additional construction in the 13th century.
The irregular west front exists because the cathedral consists of two incomplete churches, the first dating from the early 13th century, which includes the rose window from 1230; and the other begun in about 1272, on a new plan and a different axis, which was later abandoned, although by 1445 a triforium had been added to the choir and a Flamboyant west portal had been inserted. It is off-center because the architect took care to save the baptismal chapel north of the entrance. An oblong tower, composed of a Gothic portion on Romanesque foundations, and capped by a 16th-century gable belfry, completed the west façade. Also in the 15th century the nave and choir vaults were unsymmetrically connected, while in 1609, after a fire, the choir vault was rebuilt. It was not until the 1920s that its north wall was cleared of abutting buildings and a doorway added, similar in style to the west entrance.
The interior is as disconcerting as the exterior because the two sections are not on the same axis and juxtapose two styles of Gothic architecture. A massive round pillar, built at the beginning of the 16th century in an attempt to begin the transept, now stands incongruously between the two parts, lining up with the center of the nave in the west, and with the south pillars of the choir in the east. The vast proportions of the five-bay choir, with ambulatory and radiating chapels, dwarf the older nave. Of the 15 chapels, the oldest date from 1279–86, but the majority were completed during the 14th century. Most of the stained glass is 19th-century, but there is glass from almost every century beginning with the end of the 13th in the Saint Vincent de Paul chapel. This is the oldest stained glass in Toulouse.
The interesting choir stalls whose decoration includes pagan and mythological subjects were carved in walnut in 1610-13 by Pierre Monge of Narbonne. The walnut case of the organ was carved at the same time, rising some 17 meters above the floor. Restored in 1868 by Cavaillé-Coll and in 1976, the organ is often used for concerts.
The beautiful, but worn, tapestries (c. 1609) by Jean du Mazet, and the Baroque retable of the high altar are also of particular note.
References:Tyniec Benedictine abbey was founded by King Casimir the Restorer probably around 1044. Casimir decided to rebuild the newly established Kingdom of Poland, after a Pagan rebellion and a disastrous Czech raid of Duke Bretislaus I (1039). The Benedictines, invited to Tyniec by the King, were tasked with restoring order as well as cementing the position of the State and the Church. First Tyniec Abbot was Aaron, who became the Bishop of Kraków. Since there is no conclusive evidence to support the foundation date as 1040, some historians claim that the abbey was founded by Casimir the Restorer’ son, King Boleslaw II the Generous.
In the second half of the 11th century, a complex of Romanesque buildings was completed, consisting of a basilica and the abbey. In the 14th century, it was destroyed in Tatar and Czech raids, and in the 15th century it was rebuilt in Gothic style. Further remodelings took place in the 17th and 18th centuries, first in Baroque, then in Rococo style. The abbey was partly destroyed in the Swedish invasion of Poland, and soon afterwards was rebuilt, with a new library. Further destruction took place during the Bar Confederation, when Polish rebels turned the abbey into their fortress.
In 1816, Austrian authorities liquidated the abbey, and in 1821-1826, it was the seat of the Bishop of Tyniec, Grzegorz Tomasz Ziegler. The monks, however, did not return to the abbey until 1939, and in 1947, remodelling of the neglected complex was initiated. In 1968, the Church of St. Peter and Paul was once again named the seat of the abbot. The church itself consists of a Gothic presbytery and a Baroque main nave. Several altars were created by an 18th-century Italian sculptor Francesco Placidi. The church also has a late Baroque pulpit by Franciszek Jozef Mangoldt.
