During which time period did Gothic architecture mainly flourish?

Gothic architecture is primarily associated with the period from the mid-12th century to the late 15th century, specifically flourishing between 1140 and 1500. This architectural style emerged in France and is characterized by features such as pointed arches, ribbed vaults, and flying buttresses. These elements allowed for taller structures and larger windows, which were often filled with stained glass, creating light-filled interiors that were integral to the design of cathedrals and large churches during this period.

The significance of this time frame is evident in the construction of iconic Gothic structures such as Notre-Dame de Paris and Chartres Cathedral, which exemplify the innovations and aesthetic principles of the style. This era marked a transition in architectural design, moving away from the Romanesque style that preceded it and indicating a shift towards more vertical, illuminated, and ornate designs that became the hallmark of the Gothic period.
