Discover a medieval castle, now a green oasis for wildlife but still at the centre of daily life

Although you might not think it today, the mount and surrounding lands are the remnant of an early medieval wooden motte and bailey castle built by Sweyn, Sheriff of Essex. With the castle long gone, the area is now an urban wildlife haven and green lung in the heart of Rayleigh town centre, offering sweeping views across the Crouch Valley.

In the summer, the mount provides a perfect backdrop for dramatic open-air theatre productions. Make the most of your day by also visiting with the adjacent sensory garden and windmill, home to fascinating historical exhibitions (please note the windmill is not run by the National Trust).
