Turmhof, Villa in Plittersdorf, Bad Godesberg, Germany

Turmhof is a two-storey classicist villa on Turmstraße in Plittersdorf, built around 1840 on the walls of an earlier knight's estate. Its street front has thirteen window axes, with a central risalit emphasised by a portico of four unbased Doric columns and a balcony above. The slate-covered saddle roof forms an equilateral triangle, and the rear has a projecting garden portal with a Venetian window.

The Turmhof is first documented in 1569, when an image showed the estate with its two corner towers. It was a knight's estate of the Electorate of Cologne from 1690. After a fire in February 1838 it was rebuilt around 1840. From 1951 the Holy See used the villa as the Apostolic Nunciature in Germany until it moved to Berlin in 2001.

The name Turmhof recalls two corner turrets that gave the estate its name and appear in a 1569 depiction; they were removed when a stone replacement was built on the old foundations in the course of the 18th century. The villa later served as a summer residence of the Farina family and, from 1952 to 2001, housed the Apostolic Nunciature, the Holy See's diplomatic mission in Germany.

The villa stands at Turmstraße 29–31 in Plittersdorf, within a walled park of about 24,000 m²; the building itself is not open to visitors, so the view is from the street. The 1919 portico of four Doric columns on a four-step terrace faces the road and is the easiest feature to examine from public ground.

The two corner turrets that gave the estate its name appear in a 1569 depiction but were removed in the 18th century when a stone replacement was built on the old foundations. The present villa, rebuilt around 1840 after a fire in February 1838, has no towers. From 1951 the Holy See used it as the Apostolic Nunciature; the nuncio usually served as doyen of Bonn's diplomatic corps until the mission moved to Berlin in 2001.
