In the turbulent winter of 1265, Simon de Montfort, the rebel Earl of Leicester, seized control after capturing King Henry III at the Battle of Lewes
Walk in the footsteps of Simon de Montfort, rebel baron who defied Henry III in 1264 and founded the first English parliament in Lewes.
Step into the shoes of a Franciscan chronicler on a secret mission in 1265 Sussex. You arrive in Lewes, scene of the battle that changed England, to document Simon de Montfort's revolutionary parliamentary negotiations. At each stage of this 165-minute journey through 1.5 km, open your phone: medieval parchments appear on castle ramparts, royal seals reveal themselves on West Gate stones, the shadow of the Earl of Leicester emerges before Town Hall where the Provisions of Oxford were signed. From the western gate to Mount Caburn, you reconstruct the 8 places where English monarchy's fate was decided. More than an outdoor escape game: an interactive visit immersed in 800 years of parliamentary history, with anecdotes revealed at each stop and hidden sites that classic guides overlook.

The story that haunts this land
West Gate welcomes you with its 15-meter height, built around 1520 as the western gate of Lewes fortifications. Its 17th-century clock turret overlooks the entrance through which Simon de Montfort made his triumphal entry after the 1264 battle. Restored in 1892, this gate served as a watchtower for rebel forces monitoring approaching royal armies. Its stones witness the moment when English aristocracy dared defy absolute monarchy.
Market Tower rises 18 meters since 1330, former belfry that announced medieval public assemblies. Its 1582 bell rang to convene the first parliamentary meetings organized by Montfort in 1265. Integrated into the castle complex since 1802, this tower witnessed revolutionary proclamations that established barons' rights against King Henry III.
Cliffe Bridge spans the Ouse since 1780 over 150 meters, replacing the medieval ford crossed by armies during the Battle of Lewes in 1264. Its arches reinforced after 1836 floods mark the strategic crossing where English monarchy's fate was decided. Listed Grade II in 1953, this bridge symbolically links the old regime to the new parliamentary system born from Montfort's victory.
Lewes Castle raises its 30-meter ramparts since 1070, built by William de Warenne after the Norman conquest. Rebuilt in the 13th century, it became Montfort family property through dynastic alliances and served as the setting for post-battle negotiations where Henry III was forced to accept the Provisions of Oxford in 1264. Open to the public since 1911, its museum preserves artifacts of this parliamentary revolution that prefigured Westminster.
St Michael's Church, built in 1090, transformed into a field hospital during the Battle of Lewes, has preserved since 1864 a commemorative plaque for conflict victims. Its 20-meter tower, restored after the 1749 fire, reminds you that this parliamentary revolution was born in blood and conviction. You leave with the certainty of having walked where modern England took root, eight centuries before contemporary democracies.
