The entrance to Old San Juan is known as Puerta de Aguas or Puerta de San Juan (San Juan Gate). It is one of the most colorful and known of all the entrances to the walled city and it has stood tall for centuries. The gate is 16 feet tall and 20 feet thick and leads you to the romantic Paseo La Princesa.
The closest to La Fortaleza (1635), was the main access on the bay side for many years. It was there the place where the welcoming ceremonies were held for the new governors and bishops who were going to take office.
