Lovely cast iron window. It pays to look up!
 
Church Row is celebrated not just for its beauty but for its architectural and historical coherence. Laid out in the 1720s, it is one of London’s finest and most complete examples of an early Georgian terrace, with houses that largely retain their original façades, wrought-iron gates, and period lamp posts.  The Pevsner Architectural Guides famously described it as “the best street in Hampstead”, noting how the vista is framed by the tower and spire of the parish church at the far end. 
 
The window is one of those peculiarities that make the street so delightful.
 
Interesting fact...
H. G. Wells lived at No. 17 Church Row from 1909 to 1914, during a turbulent period of his life marked by marital strain and affairs. Local tradition holds that his spirit still “walks between the walls” of the house, and the property is a regular stop on Hampstead ghost tours.
