Imperial Palace Gelnhausen
The Imperial Palace at Gelnhausen (Kaiserpfalz Gelnhausen) is a 12th‑century imperial residence founded under Frederick I (Barbarossa) on a former island in the Kinzig river. The complex preserves substantial sections of its ring wall, a gate building with attached rectangular keep, and the courtyard area of the palas and foundations of a round keep. It is managed as a historic site and houses a castle museum.

As it stood in 1180
What Imperial Palace Gelnhausen looked like in its prime.
A compact red-brown sandstone complex on a low island site, enclosed by a thick curtain wall with eight bends and a series of round-arched openings. The dominant group is the three-bay gate building with a large outer round-arched entrance and an upper chapel above it, joined to a tall rectangular keep to the south. To the north the palas presents an asymmetric courtyard façade of grouped arcaded windows with double columns and a richly carved clover‑headed entrance; inside the courtyard are the low circular foundations of an unfinished round keep.
Its story
The story of Imperial Palace Gelnhausen.
The imperial palace at Gelnhausen was built in 1160–1180 under Frederick I Barbarossa on an island in the Kinzig, its buildings standing on some 12,000 wooden piles driven into the soft ground — a structural problem ever since. With Frankfurt, Friedberg, Wetzlar, Trebur and Seligenstadt it administered the imperial territory of the Wetterau, and it controlled the Via Regia, the great long-distance road between Frankfurt and Leipzig, where it passes through the Kinzig valley.
Decline began in the 14th century: in 1349 Emperor Charles IV enfeoffed the palace and town to the Counts of Schwarzburg and never reclaimed them. In 1431 the Count of Hanau and Count Palatine Louis III procured both from Count Henry of Schwarzburg, and when Johann Reinhard III, the last male of the House of Hanau, died in 1736, the Landgraves of Hesse-Kassel inherited the Hanau half and later bought out the Electors Palatine.
Substantial sections of the ring wall survive, together with the gate building and its attached rectangular keep, the courtyard of the palas and the foundations of a round keep. The outer bailey on the island, which housed the Burgmannen, remained a settlement in its own right, independent of the town of Gelnhausen, until the beginning of the 19th century. The site is managed as a historic monument and houses a castle museum.
