How the problem of keeping warm is solved in Western stone buildings

Western European stone buildings are less concerned with keeping warm, the primary problem being that of the dome, or roof, of the stone building.

In general, whether Romanesque or Gothic, due to the nature of masonry, the only way to bear the weight of the roof was to use an arch (or timber frame) to bear it. Medieval buildings, castles, dwellings, etc., tend to have thick walls that are better insulated, and warmth is not a problem. However, Gothic churches, due to the columns and buttresses, openings are many and narrow, church glasses, unfavorable to insulation. Anyway, the gothic church also requires people to stay away from earthly love, always cold, it does not matter.

So, Britain, the United States traditional homes (Tudor-style) interior decoration have fireplaces, fireplaces are the center of the whole family activities. This was the Western European solution to heating.
