What's inside the Moscow Kremlin?

On visiting Moscow for his coronation festivities, Czar Nicholas I was not satisfied with the Grand Palace (alias Winter Palace), which had been erected in the 1750s to the design of Francesco Rastrelli. The elaborate Baroque structure was demolished, as was the nearby church of St. John the Precursor, built by Aloisio the New in 1508 in place of the first church constructed in Moscow.
