Guam Discovery Day falls on the first Monday of March every year and takes place on March 1 this year. The holiday commemorates the day Portuguese explorer Ferdinand Magellan first landed in Guam and is the event that kicks off ‘Mes Chamorro’ (or Chamorro Heritage Month). Its celebration is hosted in the village of Umatac, showcasing the rich heritage of the Chamorro people through heritage walking tours along with a theatrical re-enactment of the explorer’s landing on the island. This day invites the inhabitants of Guam to honor and celebrate the rich history and heritage of the island.
History of Guam Discovery Day
Guam, an organized unincorporated territory of the United States, is located in the Micronesian region of the Pacific Ocean. The island and its people have survived centuries of colonization. The community native to Guam, the Chamorro, first settled on the island between 1500 to 1400 B.C. They remain the largest ethnic group in Guam.
The Spanish officially took over the island on January 26, 1565. Guam, being one of the two Spanish outposts in the Pacific beyond Indonesia, was used as a staging point for the colonial power’s fleet.
First observed in 1970, Discovery Day falls on the first Monday of March every year to commemorate the landing of Portuguese conquistador Magellan in Guam on March 6, 1521. As the years passed, the focus of the holiday shifted from the “discovery” of the already inhabited island to celebrating the rich cultural heritage of the native people of Guam and the country’s history. This precise reason led to the renaming of the holiday to Guam History and Chamorro Heritage Day.
Whilst the holiday marks the beginning of the colonization of the Guamanians, it is now meant to honor the Chamorro people in the context of Mes Chamorro. Its celebration is hosted in the village of Umatac, showcasing the rich heritage of the Chamorro people through heritage walking tours along with a theatrical reenactment of Magellan’s landing on the island.
