Historic 19th‑Century Villa with Clock Tower for Sale in Paço de Arcos, Oeiras

Quinta do Relógio is a protected 19th‑century estate (built 1860) located in Paço de Arcos, Oeiras — just west of central Lisbon. Designed under the direction of architect Cinatti de Siena, the villa served as a residence of His Royal Highness King Ferdinand II; the estate’s distinctive clock tower gives the property its name and remains a focal heritage element. Set on a private 5,589 m² plot, the main house offers seven bedrooms, three bathrooms and expansive historical interiors that can be sensitively restored under current environmental protection regulations. The property is listed under municipal and environmental heritage protection, which preserves original fabric but allows renovation subject to approvals. With direct access to the Cascais train line (approx. 20–25 minutes to Cais do Sodré) and a 20–30 minute drive to Lisbon Humberto Delgado Airport, the villa combines coastal lifestyle and strong connectivity. Offered at €12,500,000, Quinta do Relógio is ideal for a private family residence, a cultural or institutional conversion, or a high-end boutique hospitality project that respects conservation rules. Investment considerations include heritage restoration costs and the 2023 Portuguese Golden Visa changes — Lisbon coastal areas are now excluded from Golden Visa eligibility, affecting investor incentives. Viewings by appointment only; a rare, protected landmark offering immediate waterfront‑coastal lifestyle and historical prestige in Paço de Arcos.
