The rock art was made with charcoal, so radiocarbon dating could be used to determine its age. Most rock art is made with mineral paint, so its age cannot be accurately measured.
The oldest known rock art is in Spain, where a hand stencil has been dated to earlier than 37,300 years ago and a red disk to earlier than 40,600 years ago, using a technique known as uranium-thorium dating.

Archaeologists have discovered the remains of an Elizabethan theatre where some of William Shakespeare’s plays were first performed.
The remains of the Curtain Theatre, which opened in 1577, were found behind a pub in Shoreditch, east London, as part of regeneration works.
The venue was immortalised as “this wooden O” in the prologue to Henry V.
