Until the end of the 18th century, the town consisted chiefly of a string of houses, shops and warehouses stretching along the coastal dunes either side of the Church of St Helier and the adjacent marketplace (since 1751, Royal Square).
Ata o final do século XVIII, a cidade consistía principalmente nunha cadea de casas, tendas e almacéns ao longo dunhas dunas costeiras ao lado da Igrexa de Saint Helier e o mercado adxacente (dende 1751, na Praza Real).
