Baile Shemais · Co. Leitrim
A walled plantation town from 1622 on the Shannon, with a stone arch over the road and not much else - which is most of the charm.
Jamestown is small - a couple of hundred people, one bar, a restaurant, a stone arch over the old road and a quay on the Shannon. It sits about five kilometres south-east of Carrick-on-Shannon, and for most of the twentieth century the N4 Dublin to Sligo road ran straight through the middle of it. A bypass took that traffic away in the late 1990s, and the village has been quiet ever since. That quiet is the point.
What makes it matter is the wall. James I chartered Jamestown in 1621 and it was founded the following year as a plantation town - one of the new settlements meant to plant Leitrim with loyal English settlers after the Flight of the Earls. Sir Charles Coote, a Devonshire planter, got the grant and walled the place: twenty feet high, six feet thick, enclosing about four acres with a castle inside. Walled towns are rare in Ireland and rarer still in the west. Jamestown is one of the few, and the line of the wall plus the arch over the road are what survive.
Beyond the wall there is a Franciscan friary from 1642, a heritage trail with brass markers, good Shannon angling, and the Cottage Restaurant - a thatched cottage doing Asian-Irish fusion that has built a reputation well beyond Leitrim. That is genuinely the lot. If you want shops, hotels and a night out, Carrick-on-Shannon is ten minutes up the road. Jamestown is a stop, a stretch of the legs, and a look at the arch. Take it for what it is.
