The Canal And Graft Bastion

 The Canal & Graft Bastion

Graft Bastion, erected during the 15th century, defended and maintained on the cost of the saddle-makers guild, used to make the connection between the White Tower and the defence system of the walled city. During the 16th century a defence wall with eight towers was built in this area and it was also then that the Graft Canal was dug to drain the water running down the slopes of Warthe Hill. After the floods in 1809, the fortified foundations weakened, and the walls were propped up on supporting arches.
