In which English seaside town was Agatha Christie born?

Agatha Christie was born in the English seaside town of Torquay, in Devon.

She was born Agatha Mary Clarissa Miller on September 15, 1890, at Ashfield, the family home in Torquay. Her parents belonged to a wealthy upper-middle-class family, and Christie spent much of her childhood in Devon. The town’s coastal setting and social world later influenced parts of her fiction.

Torquay is on the English Riviera in south Devon and is now part of the wider unitary authority of Torbay. Christie’s birthplace is often described simply as Devon, which is geographically correct but less precise than the town named in the question.

Another possible source of confusion is that Christie later lived in several parts of England, including London, Berkshire and Oxfordshire. She also travelled extensively with her second husband, archaeologist Max Mallowan. Those later locations shaped her life and writing, but they do not change the fact that Torquay was her birthplace.
