Final answer:
Romanesque architecture had several drawbacks, including the need for thick walls to support heavy stone roofs, which led to limited windows and poor interior lighting, and a greater risk of structural failure when attempting larger window openings. These issues were resolved in later Gothic architecture with flying buttresses and other innovations.
Step-by-step explanation:
The drawbacks of building in the old Romanesque style were primarily concerned with structural limitations and lack of natural light. One notable negative was the walls needed to be extra thick to support the weight of the heavy stone roofs, limiting the possibility for large windows and reducing the amount of interior light. Another consequence of the heavy stone construction was poor structural integrity when builders attempted to add additional or larger windows, putting the buildings at risk of collapse. This limitation was overcome with the advent of the Gothic style, which included major innovations such as flying buttresses, allowing for higher, thinner walls and larger windows, thus solving the structural issues associated with the Romanesque style.
