In 1601 the Siege of Donegal took place during the Nine Years' War. After the Flight of the Earls from near Rathmullan in September 1607, the castle and its lands were seized by the English Crown and given to an Englishman, Captain Basil Brooke, as part of the Plantation of Ulster. Captain (later Sir) Basil Brooke (ancestor of the Viscounts Brookeborough) was granted the castle around 1611 and he proceeded to carry out major reconstruction work and added a wing to the castle in the Jacobean style. The current plan of the town was also laid out by Brooke, including an attractive town square known as "The Diamond". From the late 17th until the early 20th centuries, Donegal Town formed part of the vast estates of the Gore family (from 1762 Earls of Arran in the Peerage of Ireland) and it was during their ownership that the town took on its present appearance. Donegal Borough returned two members to the Irish House of Commons, the lower house of the Parliament of Ireland, until the Acts of Union 1800 came into force in January 1801. Evidence of the Great Famine still exists, including a workhouse, whose buildings are now part of the local hospital, and many famine graves.
