This YouTube trailer is a taster of an interactive touchscreen 3D model of medieval Galway with buildings based on a pictorial map of Galway dating from around 1651. For history buffs you might notice that the 17th century is not the medieval period but, as RealSim points out, architecturally speaking Galway is a medieval city and this map shows street layouts and buildings that would have been 400 years in the making. The model was created by Robyn Mason and her colleagues at real-time 3D simulation company RealSim and will soon be on display in Galway City Museum. It shows spots including the Church of St Nicholas, Lynch's Castle and the Red Earl's House.
