Full Moon Circle (2003)

Full Moon Circle was installed in the grounds of Houghton Hall in 2003. It used to be on the north lawn, but was moved to the south lawn some years after its original installation. It’s made from Cornish slate, and from above looks like the surface of a moon. Browse the resources about Full Moon Circle here.


Whilst these questions have been designed to be suitable entry points for Key Stages 1-4, we would encourage you to use the questions as broadly and fully as is appropriate to your group.

Key Stage 1
What can you see in the surface of the ‘moon’?
What is the moon doing down here?

Key Stage 2
How has Long created a sense of movement in the moon’s surface? How does the choice of material support this?
If this was the moon how would it change the immediate environment?

Key Stage 3
Change the distance from which you view Full Moon Circle. Can you move to make it the shape of a half moon or crescent moon?
If the moon were not here and not in the sky how would it change Norfolk?

Key Stage 4
What symbol does Full Moon Circle and A Line in Norfolk make when you put them together?
As a community how has Norfolk welcomed travelling workforces throughout history?

How does Long incorporate a sense of the universal?

Made from Cornish slate.

Slate is a metamorphic rock, formed from sedimentary clays, hardened by millions of years of pressure from the rocks above. The layered structure breaks apart along flat planes, ideal for splitting into thin tiles for roofing or into thicker slabs like these. The quarries in Delabole, Cornwall have been producing the finest quality slate for 800 years and still use traditional hand splitting, alongside modern mechanised techniques. The slate slabs in Full Moon Circle are split along their natural cleavage planes and the blue grey colour and smooth surface, reflective when wet and silvery when dry suggest the cool light of the full moon.

Flat and overlapping – calm.

Half this globe is in the dark,
one quarter always advancing
or at war with another.

At my feet the wavelets lap,
they clip and slap each other, and
in the offing they half-open their jaws.

Or is this circle our own field-map
hymned by the sun, the seas of the moon,
each blade and slate ordaining:

“It’s late, but still not too late.
Our poor planet. Care for her.
Care for her and she’ll care for you”

Teach me not to look but to see.
Teach me not to ask but breathe

until my own tides reveal
what they will and when they will.

Wholly to immerse myself,
wholly to find myself.

Not to search for words words words
but in this place simply to be.
