Who is considered a pioneer of the Baroque style in architecture?

Gian Lorenzo Bernini is recognized as a pioneer of the Baroque style in architecture due to his innovative designs and the way he integrated sculpture with architecture. His works, particularly in Rome, such as St. Peter's Basilica, exemplify the grandeur and theatricality characteristic of Baroque architecture. Bernini’s ability to create dynamic spaces and dramatic effects was revolutionary during the 17th century. He skillfully orchestrated light, movement, and complexity within his designs, setting the standard for Baroque architecture that emphasized emotional engagement and a sense of awe.

The other figures mentioned, while significant in their own right, do not primarily focus on the Baroque architectural style. André Le Nôtre was more renowned for his landscape architecture, particularly his work on the gardens of Versailles, while Albrecht Dürer is known for his prints and paintings within the Northern Renaissance, and Donatello is celebrated primarily for his sculpture during the early Renaissance. Therefore, Bernini's contributions distinctly align him with the early development of the Baroque architectural style.
