Answer:
Because these churches were designed to resist invasions and attacks, that's the reason for austere and robust buildings, with thick walls and tiny windows. Despite the lack of attraction, these churches were designed to receive enormous groups, and if we would a guide, we should introduce the visitors to the structure itself, trying to make them look to the design, the style, why the walls should be rose like that, why the windows are so small, and giving special attention to the floor in cross shape. Romanesque churches didn't have a big appeal, beyond the structure itself.
Step-by-step explanation:
The Romanesque style used elements from the Roman architecture with simple horizontal lines, arched and vaulted, supported by solid, thick walls with few windows. It's high point occurred during the 11th and 12th centuries. Beyond the fact these churches should resist to attacks, the Romanesque style represented humility and respect, that's why these churches were traditionally small.
