Saint Jones was once occupied by the Spanish Empire, with the name Santo Mateo. Spanish influence can still be seen around the province, with many towns and cities having Spanish names. For example the city of Altas Montanas in the Alta Valley of Robloxia. "Altas Montañas" is Spanish for "High Mountains", being named after the mountains that surrounded the Alta Valley. "Piedras" in Piedrasburg is Spanish for "stones". Robloxia went to war with the Spanish empire, winning Saint Jones and Northern Livetopia, which at the time was an unorganized territory. Ciudad Santo Mateo was renamed to Saint Jones City, which grew rapidly after it was taken by Robloxia.
