is a farm in Hrafnagilshreppur county in district Eyjafjordur.
Magistrate Ari Jonsson, son of bishop Jon Arason, lived there.
He was accompanying his father and brother at farm Saudafell in the
Dalir District in West Iceland in the year 1550, when the three of
them were arrested. They were brought to the seat of the seat of
the bishop of the southern see, Skalholt and beheaded.
One of the four leper asylums of the country was built at Modruvellir.
A few carved wooden boards from ancient houses on the premises have
been preserved in the National Museum.
Above the farm is a rough area with big boulders, an example of one of
many landslides in the area. One rowan tree existed at Modrufell
for centuries. It was considered holy and became a source of
myths and poetry. The oldest rowan trees of farm Skrida and town
Akureyri are descentants from this tree.
