Scarborough and Filey libraries will be transformed into Fun Palaces on Saturday 7 October, from 10am-2.30pm.
The free family events involve artists, dancers, musicians, museums, colleges and other creative people.
They feature ceramics, music, dancing, a mini-dig, card-making, coding, quilting, seed planting and a community art project.
The theme is Everyone an Artist, Everyone a Scientist.
A spokesperson said: “Fun Palaces bring together arts and sciences – but above all people – to work together, create together and have fun together
“A visit to one of the library Fun Palaces will give people of all ages an opportunity to explore art and science and take part in fun-filled events”.
Fun Palaces are part of an annual national event on the weekend of 6 and 7 October.
Last year, 362 Fun Palaces were staged across the country at libraries, public parks, shopping centres, schools, swimming pools, town centres, etc.
