Ashentbee [Ashentree?] Court
   North out of Temple Street, Whitefriars, in Farringdon Ward Without (O. M. 1677-Elmes, 1831).
   Now called " Glasshouse Alley " (q.v.). " Ashantree Court " (Horwood, 1799).
   The southern end out of White Friars is called " Cloth Workers Court " in O. and M. 1677, and " Paved Alley " in Rocque.
   Probably named from the sign, which may have indicated the existence of an ash tree in the locality.
