This summer sees the finale of a spectacular touring art installation of over 5000 ticking clocks at Penrhyn Castle in Bangor. You can be a part of this incredible artwork by donating a clock of your own and in return for donating a clock you can claim a free ticket to visit Penrhyn Castle and experience the exhibition for yourself.

Time to get involved

Harrison’s Garden is a living, growing collection of clocks that has travelled around the country visiting National Trust properties, and its tour culminates here at Penrhyn Castle. It’s been adding timepieces along the way and you can get involved by donating a timepiece of your own.

This is your chance to be a part of this work created by renowned artist Luke Jerram, inspired by clock maker John Harrison, who struggled for years to make sea navigation safer, inventing the most accurate clock the world had ever seen. This wonderful installation is a ticking, chiming feast for the eyes and ears.

Time please

Penrhyn Castle are looking for unwanted clocks of any size or shape to become part of this incredible time-based installation. It doesn’t even matter if they are working or not – they still want them!

You won’t get your donated clock back, as it will become a permanent part of this ever-growing artwork.

As a thank you for your donation, The National Trust are offering each person who donates a clock a free pass to see the installation while it is here at Penrhyn.

Don’t be late!

The deadline for clock donations is 31st May 2018.

You can drop your clock off at Penrhyn Castle at any time during opening hours. They can’t collect your clock but if it’s large enough to need special access arrangements, please email:

If you would like to donate your clock, simply pop along to the Penrhyn Castle Visitor Centre.
