Brick and stone building rapidly supplanted timber structures beginning with the Tang Dynasty. Building projects like as the Zhaozhou Bridge (finished in 605) and the Xumi Pagoda are early instances of this change (built in 636). The popularity of brick and stone construction was due to their durability and cost effectiveness. Brick and stone buildings could also be easily destroyed by fire, allowing room for new construction. Tang architects were influenced by both Chinese and foreign styles. They built using local materials such as wood, bamboo, clay, and dry-laid stone. However, they also incorporated features from other countries including Germany, France, and Italy. For example, the German architect Gunther von Hausegger may have designed the Liuhuang Temple in Hangzhou. He has been credited with many other buildings in the city including the Yuantong Temple and the Yueling Lou Church. One feature that is unique to the Tang is the use of bird's-eye views in architectural drawings. These drawings show how a structure would look from different angles or from above, giving the designer an idea of how it will look when complete. The Tang also saw the development of new types of buildings. One type of building that arose during this time period is called a "temple town". Temple towns contained temples of every size from small neighborhood shrines to large national monuments.
