Building began in 1274 on the Nogat, and in 1309 the Grand Master moved the Order’s seat here from Venice. For nearly a century and a half Marienburg was the administrative capital of a monastic state that ran the Baltic coast. In 1410, after the Order was broken at Grunwald, Władysław Jagiełło besieged the castle and failed to take it. It fell without a fight in 1457, when the Order’s unpaid Bohemian mercenaries sold it to the King of Poland. UNESCO listed it in 1997.
It is three castles in sequence, and the plan is the point. The High Castle is the convent proper — a four-winged claustral block around a courtyard, with the chapter house, dormitory, church and the well. The Middle Castle holds the Grand Master’s Palace and the Great Refectory, roofed on palm vaults springing from slender granite piers and warmed by a hypocaust system that blew heat up through floor grilles from a furnace below. The Outer Bailey held the workshops, granaries and stables that fed the whole machine. Look for the dansker towers — latrines pushed out on bridges over running water, which is a more medieval detail than any throne room.
Say plainly what this building is. It decayed into barracks and a granary, and it was rebuilt from 1882 under Konrad Steinbrecht in a campaign that ran for forty years; UNESCO’s own citation notes that many conservation techniques now standard were worked out here. Then roughly half of it was destroyed in the fighting of 1945, and the restoration has run more or less continuously since. The castle church in the High Castle stayed a ruin until a restoration completed in April 2016, including the great figure of the Virgin on its east end. Very little of what you touch is untouched; almost all of what you see is where it was and what it was.
