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 inscription above it reads “Benedictus Oui Venit In Nomine Domini” which translates to “Welcome those who come in the name of God,” a testament to the island’s Catholic roots.
