Here is an accurate map of Ireland. I tried to do one once before, but I botched a few things because I didn't know how to use the tools yet. This one is MUCH better.
Sights include St. Patrick's Purgatory (stronghold and end portal), Rock of Cashel ruins, Newgrange (nether portal), Cliffs of Moher, Giant's Causeway, Bog of Allen, and villages at Dublin, Kilkenny, Cashel, Waterford, Cork, Limerick, Galway, Athlone, Derry, and Belfast. Each village contains a library, well, blacksmith, church, and a bunch of houses (and most have some fields). Roads (mossy cobblestone) run from one town to the next, so you can keep your bearings amid all the rolling hills. There are extensive caverns under the map, and entrances at various places (Ireland's Eye, the Aran Islands, the bogs of the southwest, and other places).

There's a decorative block it's supposed to illuminate when the sun is just right, but I haven't been there at the right time to test it, so I couldn't say for sure if it worked.
