Building in stone

It's easy to think of the Middle Ages as building in stone.  After all, almost all medieval buildings that survive are the stone ones.  The cathedrals, the parish churches, the castles, are stone structures.

But in fact the majority of buildings in the Middle Ages were not stone.  As I have discussed previously, most town and village houses were "wattle and daub," wood and plaster, what would be called half-timber now.  All-wood structures were found in some places like Scandinavia, but in France and England the good big timbers were gone by the twelfth century, so people used the smaller pieces of wood for wattle and daub, though perhaps with a stone first floor if one were very wealthy.


The reason stone wasn't used more is because it was too expensive and too hard to work.  We think of the Middle Ages as built in stone because the structures that survive from them are, to a large degree, the stone ones.  Even when they are not maintained, stone buildings survive as solid ruins.


In the early Middle Ages, castles and churches were built of field stone, stones picked up from the ground and carefully set together.  In the example below, from an eleventh-century castle in Burgundy, the stone mason seems to have become creative.


In the twelfth century, castles and churches began to be build almost exclusively from quarried stone, nice rectangular blocks.  Both the inside and outside of the wall would be smooth stone, but the center was usually filled with rubble, field stone, gravel, bits of pottery, whatever was lying around.

When the Spaniards first reached the New World and saw the impressive stone buildings that the indigenous peoples of Latin America had built, they promptly decided to use some of them as foundations for their own buildings.  They appreciated good stonework when they saw it.  The church of Santo Domingo in Cusco (Peru) was build on top of the Inca temple to the sun.

In subsequent centuries there were periodic claims that Europeans had crossed the Atlantic and gotten across the Amazon basin to the Andes to teach the Incas how to build in stone.  This is wildly improbable, based on the assumption that only Europeans can figure out how to do stonework, but at least I guess is beats the aliens-from-space hypothesis.

Inca stonework, for their finest buildings, was quarried, but they did not try to make everything rectangular.  Rather they just tried to make sure all the stones fit together very tightly.  This is especially impressive since they had no iron and had to shape their stones with chisels and polishing sand.  It is especially noteworthy that the Incas were using granite (extremely hard), not the limestone (not as hard) that medieval Europe used for its churches.  The wall pictured below is outside Cusco and is about 20 feet high (and 700 years old).
