Located by the foot of the mountain Fjällsätern, on which Tureborg Castle stands, close to the Tureborg district, the area is named for Ture Malmgren (1851–1922), a prominent, wealthy and highly eccentric local politician and newspaper owner, once chairman of the Uddevalla city council and founder of Bohusläningen.

Originally proposed in 1979, a plan to survey the area was put in place in 1988, and the nature reserve was finally created in 1991.

[1] The nature reserve – administrated by Uddevalla Municipality, and about seven hectares large – is a popular hiking area.

In the north, Hålebäcken (A tributary of Bäveån) has cut through the calcareous soil, creating a system of ravines.

The shell-mixed clay provides a habitat for liverwort and toothwort in the springs, and wood stitchwort and giant bellflower in the summers.
