Final answer:
A major feature of Mediterranean architecture is its emphasis on strategic arches and openings, such as paired arched windows and rose or wheel windows, which allow for light and create bright interior spaces.
Step-by-step explanation:
A major feature of Mediterranean architecture is its emphasis on arches and openings. One characteristic in particular is the pairing of two arched windows or arcade openings, which is a remnant of Romanesque architectural traditions. These arches often feature wheel windows or rose windows with elaborate tracery, which allow for light to penetrate the buildings, creating bright and airy interior spaces. Despite the thickness of the walls needed for structural support, Mediterranean architecture balances this with strategic openings that become more numerous and larger as the structure ascends.
