Manila's mix of architectural styles reflects the turbulent history of the city and country. During the Second World War, Manila was razed to the ground by the Japanese forces and the shelling of American forces. After the liberation, rebuilding began and most of the historical buildings were thoroughly reconstructed. However, some of the historic buildings from the 19th century that had been preserved in reasonably reconstructible form were nonetheless eradicated or otherwise left to deteriorate. Manila's current urban landscape is one of modern and contemporary architecture.
