Originally built in 1926 as a village institute, the previous hall was extended in the late 1950s and dedicated to all those from the village who gave their lives in the First and Second World Wars. The hall was always the centre of Lerryn village life but by the end of the 20th century had become somewhat dilapidated. It was therefore decided to raise funds for a complete rebuild in time for the new millennium. Under the leadership of Francis Allfrey this was achieved using funds raised by the people of Lerryn and by outside funding.
In June 2000 the hall was reopened by the Lord Lieutenant of Cornwall and re-dedicated to the memory of those who gave their lives and continues to be known as the Memorial Hall.
The new building includes a snooker room with a full sized snooker table, a large hall with a stage for performances, a well equipped kitchen and three store rooms and also has an upstairs committee room. It is licensed for public performances.
In the main hall is a projector and screen for showing films, stage lights and stage curtains and plenty of chairs and tables. As well as film presentations the hall is used on a regular basis for Pantomimes and Revues and other public performances, for the Lerryn Parent and Toddler Group, Short Mat Bowls Competitions, Yoga classes, Lerryn W.I. meetings, Lerryn Art Group, Lerryn Produce Association, Jumble sales, various committee meetings and for parties and weddings.
