Silesia Walls (Polish: Wały Śląskie, German: Dreigräben) are a line of three (or sometimes fewer) parallel earthen ramparts and ditches that run through Lower Silesia in Poland, by the towns Szprotawa and Kożuchów. The walls are about 2.5 metres tall and, at their widest, 47 metres. They run for about 30 kilometres. It is hypothesized by Maciej Boryna of the Muzeum Ziemi Szprotawskiej that the Silesia Walls were the southwest border of the Duchy of Głogów and built in 1413-1467. It is possible that rather than being military in nature the wall was designed to reduce smuggling.
Famous quotes containing the word walls:
“The night in prison was novel and interesting enough.... I found that even here there was a history and a gossip which never circulated beyond the walls of the jail. Probably this is the only house in the town where verses are composed, which are afterward printed in a circular form, but not published. I was shown quite a long list of verses which were composed by some young men who had been detected in an attempt to escape, who avenged themselves by singing them.”
—Henry David Thoreau (1817–1862)
