the waters from the Leixlip Spa flow into Rye River. There is also an overflow from the canal. The Rye then flows under the Royal Canal, which is carried in the Leixlip aqueduct almost 100 feet (30m) above. The aqueduct is in fact an earth embankment, which took six years to build in the 1790s. The Rye then descends into the heart of Leixlip. Here the river was harnessed by mills. In 1758, the site was used as a linen printing mill. Later the Rye Vale distillery was built, producing more than 20,000 gallons of whiskey annually in 1837. The distillery finally closed for good in the 1890s and the distillery has since been converted into apartments. The Rye then flows under the Rye Bridge to the confluence with the Liffey near the existing Boat House of Leixlip demesne.Leixlip around 1798
