Stonecutting marks in an old quarry close to Kladruby monastery

One of oldest stonecutter technologies was simple, but elaborate. Holes, like these by Kladruby ("Logstopes") monastery, were made into a selected piece of rock and wooden wedges were then inserted into them. After being poured over by water, these wedges swelled and helped to split the stone. Such technology is sometimes still used, but wooden wedges are replaced by Cevamit - an expanding nonexplosive mixture today.
