The Miradouro da Graça is located within one of Lisbon’s most emblematic and protected heritage areas — the Convent of Graça, Lisbon Walls, and São Jorge Castle. The site’s distinct character, including its iconic grove of trees forming a valuable environmental canopy, required a sensitive and well-integrated approach.

Following specialized technical studies, the installation of the funicular was executed using a reinforced concrete structure designed to follow the hillside’s natural slope with a constant inclination, including a tunnel section at the Miradouro station. Excavations reached a maximum depth of approximately 11 meters. To accommodate varying structural behaviors, the project was divided into four independent sections, separated by expansion joints:
1 - Rua dos Lagares Station
2 - Intersection with Jardim da Cerca da Graça
3 - Beamed Slab Section
4 - Arrival Station at Miradouro da Graça

Two boarding platforms were built — one at the upper station and one at the lower — with a machine room near the lower station housing the drive unit and all control equipment.

The Rua dos Lagares Station includes a ground floor (Level 0), a basement roughly 3 meters deep (Level –1), and a funicular shaft extending more than 9 meters (Level –2). The structure features two roof levels: one covering the entrance and the inclined section, and another forming the main roof about 9 meters above ground level.
At the Miradouro da Graça Arrival Station, part of the excavation was carried out using the Munich Wall method, forming a U-shaped retaining structure open to the west. The wall transitions from a U-shaped section (Levels 0 to –1) connected by a tie beam to a rectangular closed section (Levels –1 to –2), where increased earth pressure required thicker walls.

This project, part of the “Plan for Gentle and Assisted Access to the Castle Hill”, significantly improved accessibility while preserving the area’s historic character. The intervention enhanced both the social and urban value of this iconic location, revitalizing its touristic appeal and reinforcing its importance as a heritage landmark.
