The Royal Gniezno Cathedral served as the coronation place for several Polish monarchs and as the seat of Polish church officials continuously for nearly 1000 years. Throughout its long and tragic history, the building stayed mostly intact making it one of the oldest and most precious sacral monuments in Poland.
The cathedral played an outstanding role in the history of Poland, serving as the stronghold capital of the first Piasts, and as the starting point for Bishop Adalbert’s Christianising mission to Prussia in 997. It was here that the Holy Roman Emperor Otto III came in pilgrimage in the year 1000 to visit St Adalbert’s grave, and here that in 1025 the coronation of Boleslaus I the Brave took place (and later that of his successors - Mieszko II and Boleslaus II the Bold). In 1018 part of the stronghold settlement and cathedral were destroyed by fire, and a new church was built to replace the pre-Romanesque one at the decree of Boleslaus I. This three-aisled cathedral basilica featured two towers, though little of it survives. It was damaged in 1038 during a raid on Poland by Bretislaus, Duke of Bohemia, and in 1331, when attacked by the Teutonic Knights.
Relict remains of these earlier buildings are concealed within the walls of the present Gothic cathedral, which was built around the mid-14th century thanks to Archbishop Jarosław Bogoria Skotnicki. The first stage of this project saw the construction of a chancel with an ambulatory and a series of radiating chapels around it. In later years (up to 1512) the nave and towers were built. Further restructuring obscured the cathedral’s Gothic form, which was ultimately restored in the 1950s. Chapels which were built or partially remodelled in the 17th and 18th centuries to make burial chapels for bishops and canons, are sealed off by wrought-iron screens (14th-18th century) set in Baroque portals made of dark and pale marble.
The most famous works of art in the cathedral are the Gniezno Doors and the coffin containing the relics of St Adalbert. The Gniezno Doors, fitted in the Gothic portal of the south entrance, represent one of the finest examples of Romanesque metalwork in Europe. The pair of doors, cast in bronze in c. 1170, are of uneven size and, interestingly, one of them was cast in one piece whilst the other is made up of 24 sections soldered together. The surface of each door is divided into nine low relief panels depicting scenes from the life and death of St Adalbert.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
