Pedro de Castilla, whose personal details are currently unknown, was a resident of the town of San Cristóbal de La Habana. He is the first European author to work in Havana.

His name appears in the Chapter Minutes of the 16th-century Havana City Council. These minutes record that Pedro de Castilla governed Cuban theatrical life for a period of six years. This period began on April 28, 1570, the date on which he performed a dance for the Corpus Christi festival in Havana. For this work, he was paid 132 reales, or a dozen ducats.

Pedro de Castilla, according to records, directed other performances in Cuba around April 10, 1573 and May 25, 1576, both for the celebration of Corpus Christi.

In the Chapter Acts, he dedicated his tireless work to organizing new Corpus Christi celebrations. He used scenery and costumes, theatrical machinery, and stagecraft, which were highly notable in the sacramental plays due to their religious spirit.

He used the work of artisans, tailors, shoemakers, blacksmiths, carpenters, and caulkers in his performances to stage his plays, known as inventions. He also ordered free blacks to assist him in all the preparations.

Pedro Castilla carried out extensive work within 16th-century Cuban theater, greatly contributing to its evolution and development through his contributions to the stage. He is considered the first stage director Cuban theater ever had, whose name survives to this day.
