Staff, patients and their families are coming together this week to celebrate Birmingham Children's Hospital's 150th birthday with a week of special events.
The hospital will be kicking off the celebrations today by having a commemorative aerial photo taken outside the front entrance of 150 staff, patients and families all holding red balloons and wearing red T-shirts.
The balloons will then be given out to patients on the wards.
And on Friday, staff will be stepping back in time to their favourite era for a fancy dress competition.
A time capsule will also be created that will be buried in the grounds of the hospital.
Sarah Jane Marsh, chief executive at Birmingham Children's Hospital, said:
"From a small hospital treating only a few children back in 1862, to 240,000 children and young people a year in 2012, we look forward to an even bigger, brighter future, leading the way in the care of sick children and young people across the Midlands and beyond.
"We'd love to capture the stories and experiences of patients, families and staff who have a connection with the hospital and want as many people from across the region to get involved so we can keep their memories alive forever."
