Helios at Dyffryn Gardens

What is Helios?

This is a unique opportunity to see and experience a compelling piece of art which prompts feelings of awe, belonging, gratitude and inquisitiveness. Adult or child, old or young, every visitor will be enraptured by what they see on the South Lawn of Dyffryn Gardens.

Named after the ancient Greek god of the sun, Helios offers a detailed view of our solar system's greatest star, including rare features like sunspots. The sculpture is scaled so that each centimetre represents 2,000 kilometres of the real sun's surface. 

Along with its glowing light, Helios includes a soundscape featuring NASA recordings of the sun, by Duncan Speakman and Sarah Anderson. Together, the light and sound create a unique and immersive experience, inviting us to explore the sun's hidden beauty and power up close. 

Dyffryn Gardens is a wonderful opportunity to see the seven-metre spherical artwork outside. Helios will be displayed on the South Lawn, with the spectacular South Front bedding displays and reflective water displays in the background.

Helios has been co-commissioned by National Trust, Cork Midsummer Festival, Liverpool Cathedral, Old Royal Naval College and University College London.​ 

When will Helios be at Dyffryn Gardens?

Visitors can see Helios on Friday 23 to Monday 26 May and Thursday 29 May to Sunday 1 June. These dates fall during May half-term, but because the artwork will be outside it can only be on display for four days at a time (to preserve it), so it won’t be on display for the whole of the half-term.

A sculpture like Helios takes time to put up and take down so the gardens will be closed to visitors on Wednesday 21 to Thursday 22 May and Monday 2 June. We'll be open as usual on 27-28 May with plenty of things to do for families whilst Helios isn't on display.

What time will you be able to see it?

So more visitors can experience Helios, Dyffryn Gardens usual opening hours are being adapted and expanded while its on display. These times are to be confirmed but we’ll update this page as soon as they are.

Will the cafés be open?

Dyffryn Gardens has two cafés, both will be open during the Helios exhibition but with varying opening hours. Our cafés serve both hot and cold snack-style foods including sandwiches, toasties, pasties and cakes, and hot and cold beverage which includes alcoholic beverages.

What about parking?

There is free parking in the visitor car park, with blue badge and EV parking.

Please be aware that our parking is limited but we will do our best to accommodate every car. With this in mind, we would ask everyone to park responsibly, with other visitors in mind, taking into consideration designated parking bays and areas. There may be occasions when we need to hold you at the entrance until a space becomes free or turn you away and ask you to come back later or on an alternative day.

What happens in bad weather?

While we’re all hoping for fine weather while Helios is on display it would be quite cool to see rain dripping off the sun! The artwork is lit from the inside, so it will look just as spectacular in inclement weather as it will on a dry day. However, Helios will be temporarily removed from display if the wind picks up, to ensure the safety of the artwork and visitors.

In the event of windy weather, please check Dyffryn Gardens social media and website for updates before you travel.

What else can I see and do?
