What is the "Gothic" style often mentioned in architecture?

Gothic architecture is an architectural style that originated in France in the second half of the 1 1 century and was popular in Europe from 13 to15th century. Mainly seen in Catholic churches, it also affects secular buildings. Gothic architecture occupies an important position in the history of architecture with its superb technical and artistic achievements. The structural system of Gothic church consists of stone skeleton coupons and flying buttresses. Its basic unit is to make a double-center skeleton tip coupon on the pillars at the four corners of a square or rectangular plane, one on each side and one on the diagonal, and the roof slate is supported on the coupon to form a vault. In this way, coupons with the same height can be made on different spans, and the vault is light in weight and clear in intersection, which reduces the thrust of the coupon foot and simplifies the construction. The flying crib is issued by the pier outside the side hall to balance the lateral thrust of the arch foot in the middle hall. In order to increase stability, minarets are often built on column piers. Due to the use of pointed vouchers, pointed arches and flying buttresses, the interior space of Gothic churches is spacious, simple and unified. Ornamental details such as canopies and niches are also themed with sharp coupons, and the architectural style and structural techniques form an organic whole.
