Primrose Hill Tunnel, Railway tunnel in South Hampstead, England.
The eastern portals feature grand stone structures with carved lion masks and rusticated voussoirs, built from Portland stone and London stock brick.
The tunnel, constructed in 1838 by engineer Robert Stephenson for the London and Birmingham Railway, became the first railway tunnel in London.
The tunnel's Italianate architectural design reflects Victorian engineering practices and demonstrates early urban infrastructure development in nineteenth-century London.
The 1,164-yard tunnel contains two separate bores: the northern slow line from 1838 and the southern fast line added in 1879.
Eton College's requirement for buildings to be constructed above the tunnel led to a specific boring method rather than cut-and-cover construction.
