On the banks of the River Eske stands Donegal Castle, the 15th-century stronghold of the mighty O’Donnell clan. The combination of the robust medieval tower and the later 17th-century manor house gives it a layered appearance: Gaelic-Irish at the base, with a subtle English finish on top. From the road and the bridge, you get a beautiful view of the massive walls and its position above the water, making the castle a natural landmark as you enter Donegal Town.

The Diamond forms the central square of Donegal Town: an open, triangular space where roads, shops, and cafés converge. In the middle stands the obelisk for the Four Masters, a subtle reference to the Franciscan scholars who recorded Irish history. The square breathes a calm, local atmosphere and forms a natural landmark when cycling through the town or stopping for a short break.
