Ravenscraig Castle is a ruined fortress in Kirkcaldy, Fife, dating from around 1460 and representing an early example of artillery-focused defensive architecture in Scotland. Construction began under King James II for his wife, Mary of Guelders, but the king's death just five months into the project halted the royal residence plan. The castle was subsequently completed by the Sinclair family, who constructed its distinctive massive 3.5-meter-thick walls reflecting the revolutionary impact of gunpowder artillery on castle design. Consisting of a pair of D-shaped towers linked by a connecting range set atop a rocky promontory overlooking the Firth of Forth, the castle passed through noble families before being donated to Kirkcaldy as public parkland in 1929. Now in state care since 1971, Ravenscraig Castle stands as a significant example of transitional medieval fortification.
