For one group of Year 7 pupils, going back to school after the long Summer holiday is an occasion they'll never forget.
The children from Queens' School in Watford had their first assembly of the school year in the Great Hall, on the set of Harry Potter. It is the first time a school assembly has taken place there since filming.
200 pupils were given the chance to sit at the long banquet tables where cast members including Daniel Radcliffe, Emma Watson and Rupert Grint shot many of their famous scenes.
Our reporter, Clare Fernyhough also took a tour of the set today including Pivet Drive and Dragon Alley.
