The estates Sem, Store Berg and Tveiter are to be found nearby the lake. However, situated even closer to the lake, by far - at the foot of the ridge Skaugumsåsen - is the cultural house Tangen, which during the first half of the twentieth century was the domicile of the Family Kaspersen; who among others frequently was visited by the Norwegian cultural personality and friend Alf Prøysen at social gatherings and feasts arranged by the family.
