Solar Ferreiro Torto, Sugar-mill manor house in Macaíba, Brazil

Solar Ferreiro Torto is a two-storey manor house in Macaíba with pale grey-green rendered walls, white trim and a red terracotta tiled roof. Its central section projects under a separate hipped roof and carries a shallow balcony with a dark wrought-iron railing, reached by three tall shuttered openings framed by white pilasters with carved brackets. Six evenly spaced rectangular windows with white frames and dark panes run across the ground floor.

The site originated as a sugar mill established in 1614 before being converted into a residential manor for local elites. The current structure took shape in 1847 when the property was transformed into a grand house for the region's wealthy families.

The name Ferreiro Torto, "twisted blacksmith", is not explained by the sources, which record the estate first as Engenho Potengi in 1614. In front of the house stood a French-style garden and a pelourinho, removed after the death of D. Maria Rosa do Rego Barros de Moura, lady of the mill. The manor now serves as a museum holding items from Macaíba's history.

The property offers guided tours allowing visitors to explore the manor's interior spaces. The broader complex includes outdoor areas with educational spaces and walking paths through the surrounding vegetation.

According to a great-grandson of Colonel Estevão, the manor had hiding places and a tunnel linking it to the mill's port, built by Colonel Joaquim José do Rego Barros. The tunnel is not visible from the facade.
