Saint John's House was in possession of the watercourse (DU018-020374-/0739-) which powered 3 watermills located to the W and N of the religious house and is depicted on Speed's 1610 map of Dublin City. A section of this watercourse (DU018-020739-) was excavated in 1995 by Linzi Simpson underneath the NE corner of the National College of Art and Design on the S side of Oliver Bond Street and to the W of John Street. See attached section of Speed's 1610 Map of Dublin City showing the watercourse running along St. Thomas Street between St. Catherine's Church and John's Lane West and 'The mill's'.
