History Stone and mortar
Castles, churches and bridges were built of stone, cut from quarries and shaped by skilled masons. They set the blocks in mortar made from lime, sand and water, which slowly hardened. Many masons cut a small personal mark into the stones they shaped, and these marks can still be found on old buildings.
Great churches took a very long time. Cologne Cathedral in Germany was begun in 1248, stopped for centuries, and was only finished in 1880, following the original plans.
History Timber and roofs
Oak was the main building timber in much of northern Europe: strong, long-lasting and good for frames and roof beams. Ordinary houses were roofed with thatch, while better buildings used clay tiles, stone slates or, on churches, sheets of lead.
