EmailStep inside the sun at Bristol Cathedral this October with Helios, a stunning illuminated sculpture by Bristol-based artist Luke Jerram. Measuring seven metres in diameter, this breathtaking installation features detailed imagery of the sun’s surface, allowing visitors to explore sunspots, filaments, and solar flares safely - complete with a specially created surround sound composition by Duncan Speakman and Sarah Anderson.
Presented as part of BTF+, Bristol’s festival of technology, creativity, and culture, Helios transforms the Cathedral after dark into an immersive, otherworldly space. This unique event invites audiences of all ages to experience the fusion of art, science, and wonder in one of Bristol’s most iconic historic settings.
Evening timed entry slots available every 15 minutes. Visitors are welcome to stay up to 30 minutes once inside.

Beautiful and unique installation. It was a wonder to view and hung in Bristol Cathedral gave this incredible installation a calm and stunningly unique setting.

Spectacular and atmospheric. Price maybe a little steep as for most people there won’t be a lengthy stay.

I thoroughly enjoyed visiting Helios. It’s was very atmospheric inside the Cathedral with the dim lighting and the ethereal music.
I also liked seeing the small earth to show size comparison with the sun.
Thank you. :-)

Achingly beautiful

I had no idea until leaving that it was unnecessary to pay for a ticket and that the installation would be free to view until November. I felt misled which was a pity as I had enjoyed seeing the sun even if it was a lot of money for 30 minutes

The Helios Installation was fascinating and mesmerising. I did think £8 was quite a lot to pay to look at it as there was nothing apart from the installation itself and one information board which was very difficult to read in the dark! I thought it looked beautiful in the setting of the Cathedral in the dark. The sound system could have been better as it could hardly be heard over the chatter if the visitors. I did enjoy the installation.

Loved this event and the kids enjoyed it too😁

I was expecting more than the Helios sphere and one display board.

It was lovely to see, probably not the best of the three we have seen. Not sure if it was to large for the area it was located.

Good experience.

Husband (physics teacher) and self (science technician) thoroughly enjoyed Helios from both a scientific and artistic view. Absolutely great.
Oct 2025
It was a very good installation, and if you read the info boards you appreciate the degree of accuracy, and the amount of research there is behind the exhibit. The location certainly gives it a wow factor when you walk in and see this immense globe in front of you
