Every year the Barcelona Biomedical Research Park (PRBB) opens up to the public on the first Saturday in October. Scientists and staff at the PRBB will be explaining what the centre does and visitors will be able to see the labs and equipment used there. There will also be a chance to conduct experiments and take part in other activities.
A whole day to have fun enjoying science and discovering an important infrastructure in the city.
