A unique 15th Century red-brick castle rising dramatically above the Lincolnshire countryside

Discover 800 years of the castle’s history from palatial dwelling to cattle shed; romantic ruin to restoration. The brick castle was built by Ralph Cromwell, Lord Treasurer of England, between 1434-1447 as a display of his wealth, power and ambition in unstable times.

Explore six floors of this imposing building from basement to battlements, climb all 149 steps of its spiral staircase and marvel at the views of the beautiful Lincolnshire countryside from the roof. Make sure you view the magnificent fireplaces and follow the stained glass window timeline.

Our audio guides are free to take and will transform your visit, sending you back to the castle’s medieval heyday to imagine the hustle and bustle of castle life.

After you have climbed to the top return to the Guard House for a cup of tea and a wrapped cake. You can relax in our seating area, sit in front of the fire and take a rest from all those steps.

If you want to discover more of Lord Cromwell’s Castle complex then visit the next door Holy Trinity Collegiate Church, the largest of its kind in the country. Wander around the surrounding meadows and into Tattershall marketplace to see the remains of the College buildings and the Buttercross denoting the centre of the historic market.
