Macas House is located in the town of San Joaquin de Omaguas in the province of Loreto-Nauta, Peru near where the Maranon and Ucayali rivers converge to form the mighty Amazon River.
The town was founded by Father Samuel Fitz, the head of the Evangelical Missions to South America in the 17th and 18th Centuries. These missions extended from Peru to the mouth of the Negro river in modern day Brazil and beyond.
The town itself has a population of around 800 people and has a history of famous personalities passing through such as Father Fritz and General Francisco Requena, who in the 18th century was tasked to set the borders between the Spanish and Portuguese Empires in South America. He also extensively surveyed the tributaries of the Amazon and set San Joaquin de Omaguas as his base.
Presidential candidate Humala Tasso who later became President of Peru between 2011 and 2016 also visited the town during his campaign.
Prior to the new road connecting San Joaquin to the Iquitos – Nauta Highway, the local inhabitants generally used the river to transport their goods and produce to the markets of Iquitos. However, this new transport link cuts the journey time down by many hours, as well as opening up the area to tourism which, it is hoped, will provide a much needed income to the impoverished yet historically and culturally important town, sitting at the head of the Amazon River.
