Catholic church: Our Lady of Mount Carmel and Santa Ana
While many regard Agat as the western gateway to the south, it is also the commercial center of the south. Numerous businesses - from merchants and restaurants to the seventy-room Inn on the Bay - have sprung up in the once-quiet seaside village in the last twenty-five years. Despite Agat's thriving business center, the old heart of the village that includes Our Lady of Mount Carmel Catholic Church, Convent and School, still exists.
The seaside village of Agat lies just south of Naval Base Guam. The village's main road, Route 2, meanders through several commercial and residential areas. The road also leads to a group of public buildings, such as the Agat Community Center and mayor's office and a community library and police station. Farther south, Route 2 runs along the coast of some of the finest beaches on Guam including Nimitz Beach. Nearby is the popular Agat Marina.
The village of Agat is also home to several parks dedicated to the events of World War II. These parks are part of the National Park Service's War in the Pacific National Historical Park.
It is believed that Chief Coroo headed the first clan of Agat. Beloved by his people, he was also the eldest in the clan. Chief Coroo divided the village into families, each with its own surname. Many of these survive today but are referred to as Chamorro family names, such names as Koroo, Kamachili, De'chi, Dagu, Kusiu, Min, Ato and Gotgohu, to name a few.
Spanish Governor Don Jose Quiroga then designed Old Agat between 1680 and 1684 as a settlement for rebellious Islanders whose homes he had destroyed during the Chamorro rebellion. Many of its citizens were brought from the interior village of Fena. The first church in Agat was established in late 1680. In the early 1700s this church was one of only six parishes on Guam.
Pre-war Agat was a small village with coasts lined with coconut trees that produced copra (coconut meat). The village also supported farming, ranching, and fishing. Rice paddies existed on the coastal flats as well as the flat inland areas.
