A town drawn on paper first
Wyatt's plan
The Brownes had a castle and a village called Cathair na Mart on what is now the lawn of Westport House. In the 1770s the second earl, Peter Browne, decided the village was in the way of his view, knocked it down, and hired the English architect James Wyatt to draw a new town a mile up the road. Wyatt set the Carrowbeg river into stone-walled channels, lined the banks with limes, dropped eight Georgian houses around an octagonal market square, and that was that. Built between 1780 and 1788. Still working.
How a pirate married into the gentry
Grace and the Brownes
Westport House sits where Grace O'Malley — Granuaile, the pirate queen of Clew Bay — had a castle in the sixteenth century. Her great-great-granddaughter Maude Bourke married into the Browne family and brought the land with her, which is why the current owners can claim straight-line descent from a woman who sailed to London in 1593 to talk Elizabeth I out of hanging her son. The house keeps the dungeons of her old castle in the basement. They are exactly as cheerful as you'd expect.
The last Sunday in July
Reek Sunday
Croagh Patrick has been climbed on the last Sunday in July for at least 1,500 years, and probably much longer — the Christian pilgrimage layers neatly on top of a much older Lughnasa harvest festival. On a good year 15,000 to 25,000 people make the climb, some barefoot, some at dawn. The mountain is 764 metres of loose quartzite scree on the upper third and you do not want to be on it in cloud. If you're climbing, go any other day. The Sunday is for the pilgrims.
Ireland's first proper one
The Greenway
The Midland Great Western Railway ran a branch line from Westport out to Achill Sound from 1894 until 1937, when it became one of the last casualties of the rural rail closures. The track bed sat there for seventy years. In 2010 and 2011 Mayo County Council surfaced 42 kilometres of it as a traffic-free walking and cycling route — the first greenway of its scale in the country, and the template for every one that has followed. The New York Times put it on a top-three world list. Hire a bike at the station and you'll see why before Newport.
