Established in the 1950s and operated by the Guam Department of Parks and Recreation, it is best known for its set of eight historical latte stones, which were transferred from their original site in Fena.

The Park is located along the cliffline below the Governor's residence in Agana Heights and south of the Plaza de España.

The park also includes the entrances to two sets of caves that were constructed during the Japanese occupation (1941–1944) by forced laborers and that were listed in the National Register of Historic Places in 1991 as the Agana/Hagåtña Cliffline Fortifications.

Mepo' was located in the historically densely settled Talofofo River watershed but the population is thought to have been transferred in the Reducción villagization of the Spanish-Chamorro Wars in the late seventeenth century.

At Mepo the supports and caps (two sets) were moved from their original positions to provide space for the construction of Naval Ammunition Depot Magazine 173.

Setting up the supports and either replacing the caps or placing them near the pillars will undoubtedly save the stones from vandalism or use as construction material.

The Governor also tasked the committee with the preservation of Spanish colonial structures and researching the island's history, folklore, and geology.
