Llwyn Isaf (Welsh for 'lower grove'), also known as the Library Field, is a green space in the centre of Wrexham. It is surrounded on two sides by the city's guildhall and on another by the library.
The space is most popular with students from the nearby Yale College. It is home to a bandstand and often hosts outdoor events and activities. All ball games and alcohol are banned on Llwyn Isaf.
Wrexham Council run a webcam that is pointed at the grass.
