Can you reach any castle within 40 miles of Southend-on-Sea by train?
17 of the 24 sit within 1.5 miles of a railway station, the closest being Mountfitchet Castle (Stansted Mountfitchet, 0.1 miles), Rayleigh Mount (Rayleigh, 0.2 miles), Rochester Castle (Rochester, 0.2 miles) and Tower of London (London Fenchurch Street, 0.3 miles). Those are straight-line distances from the station to the castle, so the walk on the ground is longer than the figure.
Can you go inside every castle within 40 miles of Southend-on-Sea?
Not all of them on the same terms. 2 of the 24 restrict what a visitor can see. Lympne Castle is a hotel, so there is no way in without booking a room or a table. At St Leonard's Tower you get the grounds or a booked tour rather than free run of the building.
