The greenspace Nattergaleengen (literally "The Nightinggale Meadow") separates Vallerød from the Hørsholm neighbourhood.
The village of Vallerød was probably established in a clearing in the vast forest of North Zealand some time during the 13th century.
[1] The Coast Line opened in 1887 and after the turn of the century, several of the farms in Vallerød sold off their land in lots.
In 1939, Hørsholm Municipality began to purchase land in the area which was later developed with single family detached homes.
Nattergaleengen, which separates Vallerød from Hørsholm, creates a green corridor between Folehaven and the Kokkedal estate.
