Glaumbær is an Icelandic town and church site in the middle of Langholt, west of Héraðsvötn in Skagafjörður, formerly a part of the rural municipality Seyluhreppur.

[3] The explorer Þorfinnur Karlsefni and his wife, Guðríður Þorbjarnardóttir, lived in Reynistaður before they came from Vinland and bought the land that became Glaumbær.

A short while before the Reformation, Jón Arason granted the land to Hólastóll and made it into a rectory; priests have been in Glaumbær since.

[12] The Skagafjörður Folk Museum, which acquired the Glaumbær turf houses, was founded on May 29, 1948[13] and opened its doors on June 15, 1952.

[14] The museum's turf houses contain many items; most are tools related to domestic life and techniques used in an earlier era.

The site is unique among Icelandic turf farms insofar as very small stones are used in the walls in a way that is rarely found in the municipality of Glaumbær.
