A full raft of emergency services, including the air ambulance and hazardous area response team, were called to Listley Street Car Park, with West Mercia Police operations confirming an incident on social media at around 10.20am on Friday.
A man was later taken to hospital by land ambulance, with the air ambulance not needed. Police at the scene said no-one else was involved.
In their first tweet officers said: "Please be aware Listley Street car park in Bridgnorth will be closed for some time due to a police incident."
The force later clarified, saying officers were supporting West Midlands Ambulance Service medics "dealing with a medical incident". The WMAS later confirmed that a man had to be treated and rescued from height. A WMAS spokesperson said: "We were called to a building site on Listley Street, Bridgnorth at 9.09am following a call to a patient who had suffered a medical episode at height.
"An ambulance, two paramedic officers, the Midlands Air Ambulance from Cosford with a Medical Emergency Response Incident Team (MERIT) trauma doctor, and critical care paramedic on board, and Hazardous Area Response Team (HART) paramedics responded to the scene. When ambulance crews arrived, they found a man who had become unwell whilst working around 12ft above ground level.
"HART paramedics, who are trained to access and treat patients in complex or hazardous situations, worked closely with fire colleagues to safely reach the man before treating him for his condition.
"The man was stabilised before carefully being lowered to ground level using specialist equipment. The man was then conveyed by land ambulance to Queen Elizabeth Hospital Birmingham for further care."
The car park was reopened shortly after 11am.
