The Collegiate Church of St. Bartholomew was built in coal sandstone, starting in the late 11th century (the chancel) and lasting until the late 12th century (the massive westwork, with its twin towers which were reconstructed in 1876). It underwent, like most ancient religious buildings, modifications through the centuries. Nevertheless, the Meuse Romanesque—Ottonian architecture character of its architecture remained deeply rooted. The 18th century saw the addition of two more aisles, the opening of a neoclassical portal in the walls of the westwork, and the French Baroque redecoration of the interior. The interior of the western section has recently been restored back to the original style.
The church contains numerous works of art, among which may be mentioned The Glorification of the Holy Cross, a tableau of the local painter Bertholet Flemalle (1614-1675); The Crucifixion, from another local artist, Englebert Fisen (1655-1733); and a statue of St. Roch by Renier Panhay de Rendeux.
St. Bartholomew is the site of one of the most known examples of ecclesiastical Mosan art, a baptismal font attributed to the goldsmith Renier de Huy. It was commissioned at the beginning of the 12th century (1107-1108) by the Abbot Hellin for the Church of Notre-Dame-aux-Fonts, now destroyed, where local baptisms traditionally were administered.
The font was installed in St. Bartholomew Church in 1804, after having been spared from the occupying forces of the French Revolutionary Army.
This work heralds a resurgence of Greek influences on Western art. The brass tank, resting on ten (originally twelve) ox figures, presents five scenes: the Baptism of Jesus in the Jordan, the preaching of St. John the Baptist, the baptism of the catechumens, the baptism of the Centurion Cornelius, and the baptism of the philosopher Craton.References:
The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
