Kaiserpfalz Kaiserswerth is the ruined remains of an imperial palace (Kaiserpfalz) near the town of Kaiserswerth in Germany. The site today preserves large stretches of ashlar and rubble curtain wall with rows of round-arched openings around a central courtyard. The surviving masonry shows dark volcanic stone with later red-brick repair work and abundant vegetation on the upper walls.

As it stood in 1170
What Kaiserpfalz Kaiserswerth looked like in its prime.
A roofless two-storey curtain of dark, roughly squared volcanic stone punctured by regular round-arched openings on both levels, with many arches trimmed or repaired in red brick. The façade forms one side of an open central courtyard that contains a low, rectangular paved platform edged in small basalt blocks. Masses of collapsed rubble, patched masonry and ivy cling to the wall tops; the left end has a deep recessed arched bay and the right shows the stump of a thicker projecting wall.
Its story
The story of Kaiserpfalz Kaiserswerth.
The Kaiserpfalz at Kaiserswerth, now a district of Düsseldorf, grew from a monastery founded by the Anglo-Saxon monk Suitbert around 700 AD, on a Rhine island given to him by Pepin of Herstal and his wife Plectrude. The site — its name derives from the Middle High German werth, "island of the emperor" — developed into a fortified customs stronghold on the river.
Emperor Henry II gave Kaiserswerth and its castle to Count Palatine Ezzo of Lotharingia after their reconciliation; Ezzo's son Otto returned the gift in 1045 in exchange for his appointment as Duke of Swabia by Henry III. The complex was never a permanent residence — Frederick Barbarossa is documented staying only once, on 22 April 1158 — yet his 1184 inscription declares that "Emperor Frederick increased the empire with this ornament".
Otto IV held prominent prisoners here in 1214–15, among them Otto I, Count of Oldenburg, Prince-Bishop of Münster and partisan of Frederick II, whom Adolf VI of Berg five times tried and failed to free by attack "from the water". William II of Holland besieged the castle for a year in 1247, and the Treaty of Rastatt returned Kaiserswerth to the Electorate of Cologne in 1714. Long stretches of curtain wall with rows of round-arched openings still stand.
