Gisselfeld

Gisselfeld, a former monastery, is Denmark's fifth-largest estate. Located between Haslev and Næstved, it extends into several municipalities but the main building is located in Braaby Parish in Faxe Municipality. The estate measures 3,850 hectares, including Hesede, Edelesminde, Brødebæk and Gødstrupgård, of which 2,400 hectares is forest. The three-storeyed Renaissance-style building has stepped gables, loopholes and a projecting tower over the main gate. The grounds include a moat, a well-kept park, lake, waterfall, gardens, greenhouse, and a fountain. A recent addition in its forest is a 45 meter tall hyperboloid tower.
