The ancient Oak tree in Belvoir Forest Park, Belfast, Northern Ireland. This tree is said to be the park's most well-known resident, and its trunk, which divides into three, measures a large 8.6 metres around the base. The tree is thought to be hundreds of years old.
Here, I caught the tree as the sun began to set on a fine autumn evening.
