It is part of the B509 route which continues eastwards as Adelaide Road to Chalk Farm tube station.
Much of its route runs parallel to the Midland Main Line and Kilburn High Road station is at its eastern end.
It was the route from Kilburn to the old Belsize House estate, hence its name, although a stretch of it was initially called Adelaide Road North.
[3] Laid out in the mid-Victorian era many of the early buildings were designed by Robert Yeo, an assistant of Samuel Cuming.
[6] Later Kilburn Wells, a well-known spa, was located in the area during the eighteenth century.
