Glastonbury Canal (medieval)
The medieval Glastonbury canal was built in about the middle of the 10th century to link the River Brue at Northover () with Glastonbury Abbey, a distance of about . Its initial purpose is believed to be the transport of building stone for the abbey, but later it was used for delivering produce, including grain, wine and fish, from the abbey's outlying properties. It remained in use until at least the 14th century, but possibly as late as the mid-16th century. English Heritage assess the canal remains, based on a "provisional" interpretation, as a site of "national importance".
==Construction==
Modern archaeological excavations have shown that this was a "true canal" wide and deep, with a flat bottom and sloping sides. The place where it met the River Brue, then flowing about north of its present course, was already significant: it had been an important crossing point, with a timber causeway over the river and the associated marshy floodplain, since at least the 8th century. For most of the canal's length it was dug through firm clay, following a level course along the 10-metre contour on the north-west side of Wearyall Hill, but at its end point, close to the Saxon-era market place (still extant at ) it encountered less stable soil. Here the banks were revetted with timber and a wharf was possibly constructed. Radio-carbon analysis of this wooden material indicates a 10th-century, or possibly slightly earlier, date. It was fed by springs at this north-eastern end.
