Old world charm in the new world. Streets that have seen a lot of history and major empires fighting for them. Old San Juan’s charm lies in its setting by the water, in its history, and in its well-preserved architectural jewels (including the “adoquines“, the cobblestone used to pave the streets a few centuries ago). The wavey adoquines resemble the sea around Old San Juan, reminding us of its place in the Spanish Empire as a key port.
