The University of the Third Age or U3A as it is affectionately known is an international organisation run by it’s unpaid volunteer ,mostly retired, members for their own edification and obvious joy. There is no age limit either way ( ie young or old) It is a place where anyone of any age can come to learn.
It was originally founded in 1973 in Toulouse , France and now operates all over Europe, Canada, Australia and the Commomwealth.
There are now approximately one thousand U3As branches in the UK, and approximately half a million members , all entirely self funded
There are no exams or qualifications , just pure enjoyment in learning and sharing with like minded people in a relaxed and friendly setting. The “students” teach each other drawing on their own knowledge and skills ; subjects covered would be similar to any university so the curriculum is pretty exhaustive.
Many of the tutors are extremely well qualified – some tutors have none at all but have a great talent for imparting knowledge in their chosen subject.
The London Hampstead branch also has a regular film society and Monday talks
