Strategy[]
Depending on your empire's location and your overall strategy, Walls may not be high on your priority list. Free Ancient and Medieval Walls for three of your cities, however, are welcome no matter what victory you hope to achieve. Obviously best used in undefended cities to save on 
Production costs, James of St. George's ability has good synergy with Monarchy and its legacy bonus. You should also make it a priority to claim James of St. George when playing as Georgia, because cities in which you activate his ability will be ready to build Tsikhe as soon as you discover Siege Tactics.
Civilopedia entry[]
Master James of St. Georges – or more formally Jacques de Saint-Georges d’Espéranche – was a Savoyard employed by England’s Edward I to design and build castles to keep his new but unruly subjects in line. Edward Longshanks kept grabbing chunks of Wales from 1277 to 1283 AD, when Llywelyn ap Gruffudd was finally killed in battle at Orewin Bridge. Concerned about a rebellion among the Welsh lords while he turned his attention north to the Scots, the king ordered the building of castles. Edward likely had met James – son of a master mason working in Savoy – in 1273 on a state visit, and hired him as his 'ingeniator' (chief engineer) in 1278.
James got busy building castles for Longshank’s Welsh occupation; at least 12 of the 17 English castles built in Wales during this period are his work. At Rhuddlan, James’ first effort, he perfected the symmetrical, concentric “walls-within-walls” which became his trademark. His castles soon dotted the Welsh countryside – Conwy, Flint, Harlech, Caernarfon, and Beaumaris among others. Around September 1298 James joined Edward in Scotland to set about intimidating another bunch of savages with his castles, but managed to expand the fortifications at only Linlithgow Palace and at Stirling before his death in 1308.
