In 1887, John Bartholomew's Gazetteer of the British Isles described Llanrwst like this:
Llanrwst, market town and township (ry. sta. Llanrwst and Trefriw), Denbighshire, and par., partly also in Carnarvonshire - par., 13,458 ac., pop. 4693; township, 15,837 ac., pop. 4260; town, on river Conway, 11 miles S. of Llandudno Junction, pop. 3688; P.O., T.O., 2 Banks. Market-days, Tuesday and Saturday. Tanning, malting, and the mfr. of woollen goods are the chief industries. A steep bridge which here stretches across the river Conway is said to have been erected in 1630.
A Vision of Britain through Time includes a large library of local statistics for administrative units. For the best overall sense of how the area containing Llanrwst has changed, please see our redistricted information for the modern district of Conwy. More detailed statistical data are available under Units and statistics, which includes both administrative units covering Llanrwst and units named after it.
