Marchlands is a British television series developed from the American television drama pilot The Oaks, written and created by David Schulner, and broadcast on ITV in 2011. A follow-up series, Lightfields, was broadcast in 2013. Each five-episode series explores the lives of three families, occupying the same house in different time periods. A restless spirit haunts the house, and the previous house owners appear to their successors as ghosts as well.
