St. Augustine's coastal location offered strategic advantages for Spanish colonization, including a natural harbor, defensible terrain, and access to vital resources.

Father Francisco López de Mendoza Grajales conducted the first Catholic Mass at the Timucuan village of Seloy on September 8, 1565. The landing party selected a site near the native settlement, which provided access to fresh water springs and elevated ground for observation. Spanish soldiers erected a wooden cross, marking the formal establishment of St. Augustine while Menéndez proclaimed Spanish sovereignty over La Florida.

The Spanish colonists constructed temporary shelters using palm fronds and wood within the first month of arrival. Initial fortifications included:

• Wooden palisades measuring 8 feet high enclosing a 50-yard perimeter
• Artillery positions facing the harbor entrance
• Storage buildings for food supplies and ammunition
• A chapel made from palm logs and thatch

The settlement expanded from its original location through three key developments:

1. Construction of earthwork defenses
2. Establishment of a permanent water supply system
3. Creation of agricultural fields outside the fortified area

Initial Settlement Statistics	Numbers
Fortified Area	4,000 sq yards
First Inhabitants	800 people
Initial Buildings	26 structures

The colonists adapted native Timucuan building techniques while incorporating Spanish architectural elements. This blend created structures suitable for Florida's climate and available materials.

Spanish colonial architecture defined St. Augustine's urban landscape from 1565 to 1821, incorporating defensive fortifications, religious buildings, and residential structures adapted to Florida's climate.

The Castillo de San Marcos, constructed between 1672-1695, stands as North America's oldest masonry fortress.
