Northburgh Castle, also known as Green Castle or Greencastle Castle, is a 13th/14th-century ruin in Greencastle, Ireland. Completed in 1305 by Richard Óg de Burgh, it controlled Lough Foyle and served expansion plans. Edward Bruce captured it in 1316, and it later became an O'Doherty stronghold. The castle features an oval enclosure with a twin-towered gatehouse and a later large tower. Influenced by Edward I, it symbolized a shift from pure military structures to administrative centers. Damaged by cannon fire, the castle is now managed by the Irish government and accessible from the town and shore.
The Jacques Cartier Manor House is the only existing property wich belonged to Cartier, the discoverer of Canada, in 1534. It’s a rare example of a great 16th century explorer’s home. Jacques Cartier opened up the North American continent to the French via the Gulf of Saint Lawrence. The manor house has been restored and furnished to illustrate both the everyday life and the travels of its famous owner. From the kitchen with its red clay floor, to the explorer’s bedroom, this museum has lost none of its period charm.
