Thamstorp, Manor house in Grästorp Municipality, Sweden

Thamstorp is a manor house in Trökörna parish, Grästorp Municipality, whose main building was designed by Oskar Erikson in French Renaissance style and built in the late 1870s, probably completed around 1880. The main building and park were separated from the farm in 1927 and are now owned by MOFAST, with a care home run by Ambea/Nytida.

The estate began as Brandstorp, held by Anders Eriksson Hjorthufvud from 1509 to 1515. His son Peder Andersson added the church plot Låftstomten, after which the whole property was called Lofstomten. In 1785 governor Johan Christian Adelsköld received permission to rename it Thamstorp after his wife Elsa Dorotea, born Tham. The current main building was designed by Oskar Erikson and built in the late 1870s for captain Magnus Fredrik Rodhe.

The name Thamstorp was granted in 1785 to governor Johan Christian Adelsköld, who named the estate after his wife, Elsa Dorotea Tham. The property passed through families including Wrangel, Silfverschiöld, Ostwald, von Mentzer and Belfrage. From 1927 the main building and park belonged to the city of Gothenburg, which ran a rest home for mentally ill patients there.

The main building and park have belonged to the city of Gothenburg since 1927 and today house a care home run by Nytida, owned by MOFAST; the building is not open to tourists. The surrounding farmland has stayed with the same family since 1904. The site lies in Trökörna parish, Grästorp Municipality, reachable by local roads.

The name was granted in 1785, when Governor Johan Christian Adelsköld received permission to call the estate Thamstorp after his wife, Elsa Dorotea, born Tham. Before that the property had been known as Lofstomten, a name taken from the Låftstomten plot that Peder Andersson added to the family's church land.
