Why were some churches built in stone and others in wood?

Even though they could afford to build in stone, some still opted for wood.

Værnes Church in central Norway was built in the 12th century – a key period for church building in Norway. Urnes Stave Church is shown on the right.

When a farmer saw the pile of stones that would become Sør-Fron Church, he reportedly wondered if the church was not supposed to be hollow.

That was how large the pile needed to be to build that church in the 1700s.

Back in the Middle Ages in Norway, somewhere between 1,000 and 3,000 stave churches were built, while stone churches were much less common. There were only about 300 of them.

Many of the medieval stone churches still stand today, says art historian Morten Stige.

Why was that – and what was the reason some villages got a stone church instead of a wooden one?

Stone was not an obvious choice

“Church buildings are the first communal buildings we have in Norway,” says Morten Stige.

He is an art historian and civil economist. Today he works at Fabrica Kultureminnetjenester (cultural heritage services). He wrote about the farmer in Sør-Fron in a book about Værnes Church. He has also contributed to a book about Rødven Stave Church.

The church was, of course, a place to worship God, but it was also where the whole community gathered. Given this role, it is not surprising that so many churches were built.

Why some of them were built in stone, however, is not as obvious.

It takes a lot longer to build a stone church

Constructing a stone church was a massive undertaking.

Stige has concluded that building a stone church took about eight times as many working hours as constructing a stave church.

In most cases, the choice of wood over stone was likely an economic decision, he says.

“Nevertheless, there were enough resources to build in stone in many places where wood ended up being chosen. Everything indicates that people had relatively free choice. Some chose wood, others chose stone,” he saiys.

Rødven Stave Church (on the right) could have been built in just one year, says historian Morten Stige. He estimates that building a similar church in stone would have taken eight times as long.

How long did it take to build churches?

There are no accounts or other written sources detailing church construction in Norway during the Middle Ages. Morten Stige and Øyvind Vestad have therefore had to calculate how long it would have taken to build a stave church like Rødven – from felling the right pine trees to coating the finished structure with tar.

Stige estimates that a small and simple stave church like Rødven could have been built in one year with 3.5 medieval man-years of labour. In those days, workdays were much longer than our modern eight-hour days.

He has conducted a similar analysis for Værnes Church, examining factors such as the amount of lime required for construction and the amount of firewood needed to produce it. He also looked at the sheer volume of stone that had to be quarried, transported, and carved.  

“In short, we've broken down the building process step by step. Then, we calculated the labour time in workdays and the cost in kilograms of silver,” he says.

For Værnes Stone Church, Stige estimates that construction required 130 man-years and 85 kilograms of silver. He believes the church was built in phases over 65 years. The process began with the choir, the oldest section of the church. The choir was completed with walls and a roof, making it usable as a church even before the rest of the structure was finished. According to Stige, craftsmen from five different trades were likely involved just to get the walls up: stone quarrymen, stonemasons, lime burners, lime mixers, and bricklayers. Additionally, a blacksmith was essential to keep the tools sharp.

The first step was to quarry the stone from the mountains and shape it. Stones had to be precisely cut to fit doorways. Limestone had to be burned to make lime mortar, which was then mixed before the walls could be built, one stone at a time. A carpenter was also needed since every stone church was topped with a wooden roof.

Most stone churches were built along the coast, explains Stige. A  relatively high number were also built in Telemark and along the major waterways such as Mjøsa, Norway's largest lake. The coastline and river systems served as transportation routes, facilitating trade.

According to Stige, researchers continue to debate whether stone churches held a higher status than wooden churches.

Could afford stone – chose wood instead

Urnes Stave Church is famous worldwide – partly because of its intricately carved north portal.

This stave church was built on a very important farm.

“The estate belonged to one of the wealthiest families we know of in Western Norway. They could have afforded to build in stone, but instead, they built several wooden churches in succession on the same site,” art historian Kjartan Hauglid told sciencenorway.no in 2024.

Hauglid also pointed out that there is a symbolism in both the use of wood and the reuse of the portal from an older church.

Stige agrees.

“At Urnes, where they undoubtedly had the means to build in stone, cultural factors must have influenced their decision. Elsewhere, some communities likely considered a stone church but preferred to allocate their resources elsewhere,” says Stige.

Wealthy landowners funded the construction of Urnes Stave Church, suggesting that cost was not the primary factor in choosing building materials, researchers believe.

More stone churches than stave churches

During the Middle Ages, stave churches far outnumbered stone churches in Norway. Today, the opposite is true. Of the estimated thousand stave churches once built, only 28 remain, while nearly half of the 300 medieval stone churches still stand.

“Stone is a durable material. Even if a stone church burns, it can be rebuilt,” explains Stige.

Stone churches were generally larger than stave churches. As congregations grew and seating became essential, stave churches became impractical, while stone churches adapted more easily.

Old Bø Church in Telemark, built in the 1100s, is among the few that have remained largely unchanged.
Ski Church, built around 1150, has undergone significant modifications, like many other medieval stone churches.

Apart from the churches, stone buildings were rare in rural Norway before the 20th century, says Stige.

“They must have been considered treasures. While many stave churches were torn down, people were much more reluctant to demolish stone churches,” he says.

Played a role in society that is hard to imagine today

Stone construction was rare in Norwegian architecture. So where did the tradition originate?

It was introduced with Christianity, says Stige.

“The practice came with the church. The king was the primary supporter of Christianisation, bringing the first priests and masons from abroad,” he says.

“With so many churches for a relatively small population, wouldn’t this have been incredibly expensive?”

“The church was the most important cultural structure and meeting place in society. People invested heavily in churches, but they also gained a great deal from them,” says Stige.

“Churches played a natural role in daily life that may be difficult for us to imagine now. Whether you were a builder, a priest, or a member of the congregation, having a church to be proud of was significant,” he says.
