Welbeck Street has historically been associated with the medical profession.
The street runs approximately north-south between New Cavendish Street at the northern end, crossing Wigmore Street near Wigmore Hall just to the east, becoming Vere Street continuing southwards.
The London Welbeck Hospital, is located at 27 Welbeck Street, and the Welbeck Street Hospital for Diseases of the Nervous System was located on this street as well; the offices of the British Institute of Radiology were formerly located there. The Welbeck Clinic is located at No. 20.
There is a Greek Orthodox Chapel in Welbeck Street that dates back as far as the early 19th century when the building formed part of the Russian embassy. The chapel was rebuilt in 1864 and features a particularly fine iconostasis. The chapel is located behind No. 30, on the east side of the street near the northern end, and can be seen from Marylebone Mews.
