Haus Carstanjen

Haus Carstanjen is a three-story stone villa in Bad Godesberg featuring steep slate roofs and prominent towers. Long colonnaded galleries overlook the Rhine River and shape the building's distinctive appearance.

An original structure from 1716 was transformed by Wilhelm Adolf von Carstanjen into a classical castle in 1881. This conversion reflects the rising wealth of merchant families in the region.

The villa served as a meeting place for writers and artists during the early 1800s when the Schaafhausen family owned it. This artistic role made the estate an important center for creative minds of that era.

The building now houses United Nations organizations, particularly the UNFCCC secretariat, following extensive renovation by the federal government. Access is therefore limited and depends on the operating hours of these institutions.

On the grounds stands a richly decorated mausoleum built between 1894 and 1896 that serves as the final resting place of the Carstanjen family. This structure is an overlooked architectural detail that underscores the family's importance.
