Plaza de Armas (Arms Square), San Juan (must see)

Arms Square is the de-facto central square of San Juan. Over the years, it has changed several names relative to the functions it served. Initially, in 1521, it was called Vegetables Square. Then, during the 17th-19th centuries, it was known as Arms Square, for being the grounds for military drills. After that, in the early 20th century, it turned back to being called Vegetables Square once again, serving as a marketplace, before it finally re-assumed the Arms Square title.

The plaza is modeled on the classic squares of Madrid and Mexico City. Although it factually existed for centuries, it was not until 1840 that the city council approved its proper development, which started in 1851. It was at that time that the four bronze statues, oil-coated to simulate marble, representing Commerce, Industry, Science, and the Arts, arrived here (there were a total of eight statues to be installed, but the other four were lost). In 1872, the original statues were replaced with the new marble ones, representing the Four Seasons, put in the four corners of the square.

In 1955, two circular fountains and two lampposts in the center were added. The four statues were then configured in a circular fountain outside the Palacio de la Real Intendencia, which is the seat of the Department of State of Puerto Rico, on the western side of the square.

A highlight of the northern side is the Casa Alcaldía – home of the San Juan City Hall. Built in 1789, this Spanish colonial-style edifice with twin turrets resembles its sister building in Madrid. The tinkling of the fountain, the comfortable seating in the shade of the trees, and the presence of several old-style coffee booths selling snacks have long attracted tourists as a good spot for a sightseeing break when you can stretch out your feet and soak up some of the everyday comings and goings.

The laid-back atmosphere of the place also made it a popular gathering venue with locals, offering a chance to buy kids some traditional treats (like sesame-seed lollipops or coconut candies), watch shows, play dominoes, or chit-chat with friends.
