Holywood is a town in Northern Ireland that makes up part of the city of Belfast. It is a coastal village that was popular in the 18th and 19th century for its location as a resort and vacation spot. In Dinah Craik's The Half-Caste, Miss Pryor takes the Le Poer children and Zillah to Holywood to help Zillah overcome typhus fever. It is also where Zillah is almost seduced into marriage by Lieutenant Le Poer. Today Holywood is a residential area that hosts an annual jazz and blues festival.
