  • The Wellcome Collection is a museum based at 183 Euston Road, London, displaying an unusual mixture of medical artefacts and original artworks exploring ‘ideas about the connections between medicine, life and art’.



The Globe Theatre


  • Founded by the pioneering American actor and director Sam Wanamaker, Shakespeare’s Globe is a unique international resource dedicated to the exploration of Shakespeare’s work and the playhouse for which he wrote, through the connected means of performance and education.
  • Taking on the task of cleaning a building which is an authentic reconstruction of Shakespeare’s original 1599 playhouse means Principle Cleaning Services had to abandon some of its modern cleaning techniques in favour of old-fashioned elbow grease.
