The Historical Archive on Tourism (HAT, German: Historisches Archiv zum Tourismus) is sited in the city of Berlin at the Technische Universität Berlin where it is housed at the Center for Metropolitan Studies (CMS) and the Zentrum Technik und Gesellschaft (ZTG).

The HAT had been founded in 1986/87 at the Freie Universität Berlin; in 2011 international protests helped to avert a planned shut-down of the archive[1] and the following year it moved from the Free to the Technical University.

[2][3][4] Since 1999 the HAT is headed by the historian Hasso Spode and was co-financed by the Willy-Scharnow-Foundation.

Step-by-step the collection was enlarged with material about historical travel and tourism research.

The HAT is gathering various materials ranging from Baedekers to private photo albums.
