The former Lectoure Cathedral dominates the town and the belfry tower of 1488 can be seen at a distance as the town is approached. The repairs and modifications of the cathedral go back to the 12th century. The unadorned west front erected in the 15th century has been modified through the ages, and niches above the door have all but melted away due to the fragility of the limestone.
The nave was vaulted at the end of the 12th century, then repaired in 1480. Vaulted chapels were added at the beginning of the 16th century and more alterations followed in the 17th and 18th centuries. The choir and apse were also reconstructed at the beginning of the 16th century, and the five square apsidal chapels were completed. The ambulatory was created in 1600 by introducing ten cylindrical piers, and the carved early 17th century choir stalls were placed here in the 19th century. The stained glass is typically 19th century with a Tree of Jesse in the Chapelle de la Sainte Famille.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
