Smoking shelters being installed at Royal United Hospital in Bath
Three smoking shelters are being installed at the Royal United Hospital (RUH) in Bath to stop people lighting up outside the hospital's entrances.
One shelter will be outside a maternity unit, another by the main entrance and a third by an entrance on Coffin Lane.
The hospital became a smoke-free site in November 2006 but claims it has "proven impossible to maintain".
Howard Jones, from the RUH, said: "We have decided to try them to see if it will make a difference."
He added: "We are not prepared to accept patients, visitors, and staff having to walk through smoke to enter or leave our hospital. Smoking shelters are a pragmatic response and we have decided to try them."
