Since 1986 Gravina Cathedral has served as a co-cathedral of the Diocese of Altamura-Gravina-Acquaviva delle Fonti. It was built here at the end of the 11th century by Humphrey of Hauteville, Count of Apulia and Calabria, and thus lord of the town. This church was destroyed in the years 1447-1456 by a fire followed by an earthquake, after being refurbished in a Renaissance-Romanesque style. Of the original church only a few Byzantine capitals and frescoes remain. The present cathedral was built in the thirty years following, under the supervision of the bishop Matteo d'Aquino.
The main façade has a large rose window. The altarpieces are made from 17th-century intarsia with polychrome marble and mother of pearl. The ceiling has framed canvases. The church has an altarpiece carved in Bitonto stone (1468) by Guido da Guida. There is a San Michele (1538) carved in mazzaro, a local stone, and attributed to Stefano da Putignano. Along the north nave is a Byzantine fresco of the Madonna del Piede. The oak choir-stalls were made in the 15th century and rebuilt by Bishop Antonio Maria Manzolio (1581-1593).
The adjacent sacristy has a ceiling refurbished by bishop Manzolio, and elaborate presses. The bell-tower was built from a Norman watch tower.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
