Among the valuable items are an alabastar altarpiece most likely dating from the 13th century, and a pulpit estimated to be of Dutch origin from the year 1696.
The pulpit was a gift from Lárus Gottrúp, a lawyer who resided at Þingeyrar Monastery (Þingeyraklaustur) from 1683 to 1721.
A silver chalice and an altar linen from 1763 are also among the church's historically valuable possessions.
Construction of the church took 13 years and required transporting stone from Nesbjörg throughout the winter of 1864–65, by sled over the ice-covered lake Hóp on an 8-km journey.
Stonemason Sverrir Runólfsson assisted with the planning and built the church walls.
