St George's Hospital has become the first hospital with an interactive indoor map.

Patients and visitors can now use Google Maps or apps to find their way around the 14 hectare hospital site, to find a wing, ward, clinic or department they need.

St George's Healthcare NHS Trust has joined forces with Google and the indoor map was published as part of the search engine's indoor mapping programme, that shows buildings, wards and points of interest such as stairs, lifts, toilets and cash machines.

The maps are available on the Google Maps website, and will be available on the Google Maps Android app and the Google Maps iOS app later this month.

The indoor map layer is activated when zooming in on the St George's Hospital site.

On mobile phones a sidebar allows for different floors of the hospital to be loaded while zooming in on the floor level shows the wards and points of interest on the map.

Speaking about the new indoor maps Colin Wren, St George’s new media officer and project lead, said: "St George's Hospital is the biggest hospital site in London and offers a huge number of services for over a million people from across south west London and Surrey every year.

""The indoor maps follow a number of other initiatives that St George's have done to bring information about the hospital to our patients, visitors, staff and members of the public via the social networks, apps and electronic platforms that they use everyday."
