House & Family History: The Thorolds, one of the oldest surviving families in Lincolnshire, have made Marston their seat since the 14th century. The House today is mostly Tudor, reductions having been made during the Georgian era by the demolition of the Elizabethan wings and splitting the Great Hall horizontally to add a staircase and bedrooms. A 17th century overmantel carved with the Thorold arms was brought from Blankney House in 1950, when that house was demolished. On of the most important rooms at Marston is the Burston Room, which celebrates William Thorold of Little Ponton and his wife, Flora. This 17th century room was brought to Marston in the 1960s from Burston, Flora's family home in Devon. The insertion and restoration of Burston Room was supervised by Francis Johnson, who did much work at Marston.

Garden & Outbuildings: The gardens contains the oldest laburnum in England and a fine collection of trees.
