Step-by-step explanation:
The Forbidden City in Beijing, China, is a monumental architectural achievement of the Ming Dynasty constructed primarily between 1406 and 1429.
Key materials used in the construction include stone masonry, marble sourced from nearby hills, specially made bricks, wood from the Phoebe Zhennan trees, and ceramic tile for the roofs, specifically the imperial yellow glazed tiles which denoted the emperor's authority and the importance of the site.
