Conversationshaus Norderney, Cultural center in Norderney, Germany.

The Conversationshaus is a building with a distinctive L-shape located at the southern edge of the square, featuring rounded arcades and a grand portico. Inside, several halls with different functions serve visitors, including the Grand Hall and the White Hall.

A first wooden Kurhaus was built in 1800 on the advice of Friedrich Wilhelm von Halem, founder of the sea bath, with two seawater baths heated by peat, a billiard room and a playroom. A first solid Conversationshaus followed in 1822 and was extended before 1850; the arcades toward the Kurplatz were added in 1837, the eastern annex and the roof turret in 1856. King George V of Hanover, who summered on the island from 1836 to 1865, is portrayed in the White Hall.

The name Conversationshaus, used until after World War I, referred to the conversation and social rooms of the spa. In the White Hall hangs a portrait of King George V of Hanover, who made Norderney his summer residence between 1836 and 1865 and stayed on the island with his court for several years. Since 12 May 1978 a casino has occupied the corner pavilion.

The building is easily accessible and houses different areas, including a tourist information center and a library with varying opening hours. Visitors should check current operating times before their visit, as these can vary by season and area.

In 1841 the tower of the Conversationshaus, together with the Schwarze Düne on the Alten Postweg, served as a measuring point for the Gauss land survey led by Major Müller. The building also houses a casino in its corner pavilion since 12 May 1978.
