Hagatña was formerly known as Agaña and many people still refer it like that. It has been the most important town on Guam, ever since the Spanish tried to re-model the island in the name of God. Hagatña is a small place and it can easily be explored on foot in a few hours.

There are numerous nice parks and historic buildings in town. In the center of Hagatña are the remnants of the Casa Gobierno, or the Governor's Palace. It was originally built in 1736, but later it was destroyed. Some of the oldest ruins on Guam are the mysterious stone pillars, or lattes that were moved there from an ancient Chamorro village around 500 AD. It is thought the pillars served as the foundations for some impressive native homes. The lattes are in Latte Park, which was named after them. Adjacent to the park is the Plaza de España. It was the location of Guam's first Catholic church, which was built on land, donated by Chief Quipuha. The original church doesn't exist anymore, but on the site stands now the Dulce Nombre de Maria Cathedral.

A statue of Chief Quipuha can be seen on Hagatña's main thoroughfare, Marine Drive. It is in the southeastern corner of Paseo de Susana Park. In the north of the park you will find a miniature Statue of Liberty, while nearby, on the site where he held mass in 1981, stands a revolving statue of Pope John Paul II.

There are several hotels and restaurants in Hagatña. Guam's capital is more or less in the center of the island.
