In April 1757, Spanish explorer Don Francisco Maria Celi documented a trip into Tampa Bay and up the Hillsborough River. Celi's expedition came to Tampa Bay from  Cuba. The party he led up the Hillsborough River was seeking pine trees suitable for use as masts on his ships. The expedition was for the Spanish Royal Navy. Celi reportedly erected a cross at a site he named el Pinal de la Cruz de Santa Teresa (the Pine Forest of the Cross of Saint Theresa).
