Cidade Velha — Santiago, Cape Verde — architecture competition site
Challenge 01

Linha doHorizonte

The Site

A historyfacing the ocean

Cidade Velha, on the island of Santiago, is one of the most significant places in the history of Cape Verde. Founded in the 15th century as Ribeira Grande, it was the first urban settlement in the archipelago and soon became a strategic center along the Atlantic routes, where trade, religious power, military defense and culture converged.

Its landscape still preserves traces of this memory: the ruins, the system of forts, the stone, the relationship with the ocean and the morphology of the coast all reveal a deep and fragile identity.

Since 2009, Cidade Velha has been a UNESCO World Heritage Site: designing here means engaging with a unique context, where every new architecture must arise from respect for history, landscape, materiality and the horizon.

This is the site chosen for the first ARCH CHALLENGE architecture competition in Cape Verde: an open call for architects, designers and students worldwide to reimagine this extraordinary place.

Residential architecture integrated into the landscape

The Challenge

Design with the land,not over it

The challenge begins with the desire to imagine a residential complex capable of belonging to the place before occupying it. The new units should engage with the natural morphology of the land, following its slopes, views and orientations, in order to build a balanced relationship between architecture, landscape and everyday life.

We are looking for proposals that can interpret the territory with respect, through sustainable materials, coherent construction solutions and integrated open spaces. The project should also consider the long-term experience of living in this place: light, shade, privacy, ventilation and the connection with the ocean.

Functional aspects, such as access, internal paths and parking areas, should be part of the design, not secondary elements, contributing to the quality and real feasibility of the intervention.
