What is a common feature of Gothic architecture seen in structures like Notre Dame?

Pointed arches are a defining characteristic of Gothic architecture, as exemplified in structures like Notre Dame. This architectural element allowed for the construction of taller and more intricate designs compared to previous styles, providing not only an aesthetic appeal but also practical advantages. The pointed design distributes weight more effectively, enabling the walls to be higher and thinner, which makes room for expansive stained glass windows that are a hallmark of Gothic structures. This innovation in arch design contributed to the verticality and light-filled interiors that are synonymous with Gothic cathedrals.

In contrast, the use of rounded arches is more typical of Romanesque architecture, which preceded the Gothic style. Large dome structures are more associated with Byzantine architecture, and flat roof designs are common in various other architectural styles but do not reflect the key features of the Gothic tradition.
