The Campos Historical Museum (Museu Histórico de Campos dos Goytacazes) is the heart of the cultural memory of the city of Campos dos Goytacazes. It is housed in one of the region's most beautiful buildings — Solar do Visconde de Araruama, built in 1760. This architectural landmark, once the home of a sugar mill owner, today serves as a window into the past of the entire eastern part of Brazil.

The exhibition covers a vast timeline: from prehistoric settlements and the life of the indigenous Goytacá tribe to periods of economic boom associated with sugarcane and coffee. The museum officially opened its doors after a global restoration in 2012 and has since been a free public space for everyone wanting to learn about the region's history through authentic artifacts, documents, and photographs.
Here, you can see unique archaeological finds from "sambaquis" — ancient shell mounds dating back thousands of years. The museum building itself is recognized as a national cultural heritage site, and its interiors, with preserved wooden structures and grand halls, are valuable 18th-century exhibits in their own right.
