A "stave" is the upright timber that forms the framework of the church. The construction has survived all these years because the staves were set in stone. The church roof is capped with Viking-inspired dragon heads, much like ships. The dragon's heads provided drainage and ornamentation:
Here's a closeup of the roof shingles which were tarred to prevent rot (the church was undergoing some preservation when we visited, which is why there's scaffolding in the photos):
The interior of the church is quite small--probably holds about 30-40 people. It is still used today for small ceremonies like christenings and weddings. The staves are held together by large pincer beams. The stave framework was probably assembled on the ground and then raised with poles:
Here's a closeup of the church interior. The diagonal cross braces are named for St. Andrew who was crucified on a diagonal cross. The only source of light is the upper port holes, reminiscent of a ship. If you look up on the inside of the church, the exposed ribs remind you of an inverted ship:
The pulpit is from 1550s. There would not have been a pulpit in Catholic (medieval) times:
The churchyard gravestones and markers were just as interesting as the church itself. Many stones and markers were hundreds of years old. Up until the beginnings of the 19th century it was common to bury the dead under the church floor until the practice was banned. Stillborn infants or babies that died before being baptised could not be buried in the consecrated ground of the churchyard. Tiny coffins are still placed under the floor in modern times.
Some closeups of the most unusual stones and markers:
Finally, here's an example of a living thatched roof cottage on the church grounds.
