11.02 Holyhead 1923 published 2001; introduction by Alan Godfrey

Although it has an ancient history, Holyhead really developed as a major port in the 19th century. Indeed, until the end of the 18th century facilities were so basic that passengers had to be carried ashore piggy-back style at low tide. Enlargement of the harbour, Telford's road improvement and finally the railway brought real prosperity and by 1851 the population was 8,863. Thereafter growth was more modest - the population was 11,077 in 1911 - and the town began to decline after the creation of the Irish Free State. This double-sided map shows the town just after its peak; the fine detail of the inner harbour, and of the small town with a rocky hinterland, will appeal to transport historians as well as local people.


  • 19.10 Llanfair-pwllgwyngyll published 2004; introduction by Derrick Pratt
  • 19.11 Menai Bridge / Porth-aethwy 1913 published 2004; introduction by Derrick Pratt

    These two maps link up with each other and with the map of Bangor (see Caernarvonshire). For an index grid of the group visit this link. Sheet 19.10 is often abbreviated as Llanfair PG - or extended to Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch but I am not sure that many search engines will pick that up!
