Bolongaropalast, Baroque palace in Höchst, Germany

The Bolongaropalast is a baroque palace in Frankfurt-Höchst with a north facade spanning 117 meters across three wings arranged in a U-shape. A terraced garden on the southern side complements the structure, which displays the symmetrical proportions typical of baroque design.

Brothers Josef and Jakob Bolongaro, tobacco manufacturers, built this palace between 1772 and 1774 after receiving citizenship rights from the Elector of Mainz. The structure marks the rise of prosperous merchants establishing themselves in Höchst during the late 18th century.

The palace features elaborately decorated rooms with mirrors and ceiling frescoes that reflected the wealth of its owners, while the chapel continues to serve as a venue for concerts and literary events today.

The palace was cleared in 2016 for restoration, with construction starting in February 2017; as of autumn 2024, press reports suggest completion is unlikely before 2028. The 240 rooms are being fitted with a museum wing, a music room and an events hall. The building stands on the south side of Bolongarostraße, with the terraced garden dropping toward the Nidda's mouth.

The palace's park holds the Triton-Brunnen, a neo-Baroque fountain made in 1909 by Frankfurt sculptor Josef Keller. Its round basin is dominated by a reclining dolphin ridden by a water-spouting Triton. In the west pavilion, where mayor Walter Kolb once lived, a registry office now operates.
