In Lambarfjärden are Lambarön and Hässelby islets, and on Lovön's northern tip is the community of Lambarudd, named after the bay.
[2] On a current map published by the city of Stockholm, however, it appears that Lambarfjärden also runs south of Hässelby islet.
The name Lambarudd comes from the fact that it was very appropriate to block off the cape from wild animals in the spring and let the sheep lamb in this place.
Over time, Lambarudd became a tenant farm with agriculture and one of Lovö's largest commercial gardens with ten greenhouses, outdoor cultivation with bench windows, flower cultivation, many berry bushes and fruit trees, employed staff, and gardening students.
In connection with the road project Förbifart Stockholm, a bridge was initially planned over Lambarfjärden between Lovön and Grimsta nature reserve, but in 2009 a tunnel under it was proposed instead.
