 The 1813 plan by William Hastie was deemed inadequate for the task, thus the Commission hired numerous local architects and topographers who produced the final, 1817, master plan (incorporating Hastie's ideas of clearing the Central Squares of Moscow).In 1816–30, city planners set up the Garden Ring, a circular highway in place of an old fortification rampart, and widened many other streets.Later in 1817, the city held groundbreaking ceremony for Alexander Witberg's Cathedral of Christ the Saviour, a monument to the 1812 War in Sparrow Hills.
