Pedra de Itaúna, Natural summit in Barra da Tijuca, Rio de Janeiro, Brazil.

Pedra de Itaúna is a rock formation and hill of 57 metres above sea level in Barra da Tijuca, at kilometre 11 of Avenida das Américas in western Rio de Janeiro. It stands beside the Lagoa de Jacarepaguá, and the planned neighbourhood named after it, with buildings, houses, local shops and the Escola Parque, was built around its base.

The formation served as an isolated geographical landmark in a sparsely developed area but later became a reference point for the planned expansion of Barra da Tijuca starting in the 1970s. Rapid urban growth around the rock transformed the region from rural land into a modern residential neighborhood.

The rock gave its name to the planned neighbourhood built around it, Pedra de Itaúna, which has apartment buildings, houses, local shops and the Escola Parque school. The name Itaúna comes from the Tupi language, meaning dark stone. The summit stands 57 metres above sea level, beside Lagoa de Jacarepaguá.

Pedra de Itaúna stands at kilometre 11 of Avenida das Américas, in Barra da Tijuca, beside Lagoa de Jacarepaguá. The rock rises only 57 metres above sea level, about 48 metres above the flat land around it, so the walk up is short rather than a mountain hike. The planned neighbourhood of the same name, with its buildings, houses, local shops and the Escola Parque, occupies the ground at its foot.

From the summit you can see both the Atlantic Ocean and the expanding urban grid of western Rio de Janeiro in a single view. This dual perspective reveals how nature and city development coexist in the same space.
