The Obras Novas (New Works) Palace, also known as the Queen’s Palace, at the mouth of the Vala Real river (late 18th century, early 19th century), was part of the New Works of the era.

This palace served as a control point for the traffic of vessels, people and goods that passed along the Vala Real, and also as a warehouse and inn to support the old steamers that made the circuit between Lisbon and Vila Nova de Constância.

Its size and the natural charm of the surrounding area attracted various figures of nobility who would spend long periods of time here to rest.

The palace, of neoclassical architecture, demonstrates robustness, sobriety and a monumental quality, in spite of its advanced state of decay.
