Runnymede by the River Thames was the site of the signing of the Magna Carta*, a step towards limiting the power of monarchy (though still some way to go towards its abolition!) and enshrining the principle of trial by a jury of peers.
A recent art work there by Hew Locke, The Jurors, consists of 12 chairs decorated with images relating to struggles for justice and equality.
The front of one chair features the Egyptian goddess Ma'at on the front and the slave ship The Zong on the back.
Another features a refugee boat:
All sadly relevant as refugees continue to die crossing the maritime deathscapes of the Mediterranean and the Channel, and the British government schemes to deport asylum seekers to Rwanda.

* I recommend The Magna Carta Manifesto by Peter Linebaugh for a broader understanding of the significance of this historical moment.
