New York has its ‘green lungs’ in Central Park. Hamburg has its ‘green heart’ in Planten un Blomen. The park’s history dates back to the 17th century, though at that time there was no park, but defensive walls surrounding the former center of the city. Since then the grounds have become a beautiful retreat easily reachable within the city, a mecca for those who love to take walks and discover another place for sitting down with a book underneath a tree. Or just wander around, enjoying one of these views.
