Covent Garden and the Seven Acres in Long Acre.

Early History

The Bedford Estates

The garden of the Convent of St. Peter, Westminster, consisted of about 40 acres between St. Martin's Lane and 'Aldewichstrate' (now Drury Lane).  

The boundary is roughly defined by Drury Lane, Floral Street, St. Martin's Lane and a line drawn south of Chandos Place, Maiden Lane, Exeter Street and thence via Aldwych back to Drury Lane. 

It was marked by an earth or mud wall, the top of which was thatched with straw. (fn. 4) There was at least one gate on the east side,  probably where Aldwych now meets Drury Lane, near the east end of White Hart Yard (see Plate 7), and it is likely that another gate stood where later (Little) Chandos Street entered St. Martin's Lane.
