ICOMOS Portugal has requested clarification from the Porto Municipal Council regarding construction interventions in the city's UNESCO-listed historic center, including unauthorized demolition work at the Confeitaria Serrana that has raised concerns about heritage preservation standards.
The International Council on Monuments and Sites Portuguese chapter responded to media inquiries by confirming it has requested the municipality provide details on recent building works and their compliance with heritage protection procedures. The organization flagged ongoing concerns over the management and preservation of Porto's historic core, a site inscribed on UNESCO's World Heritage List since 1996.
The Confeitaria Serrana Incident
The Confeitaria Serrana, a historic café on Rua do Loureiro, was stripped of its interior—including historic architectural elements—leaving only the façade standing. The café, holder of the "Porto de Tradição" seal, underwent this work as part of the "Creative Circuit of São Bento" project.
Pedro Duarte, mayor of Porto, told the Municipal Assembly that city inspectors reacted with surprise upon discovering the unauthorized demolition. The council issued a contraordenação notice (administrative infraction) against the Grupo Lionesa for the illegal interior demolition of the protected building.
Duarte clarified that the licensing terms previously approved did not permit wholesale interior destruction of this nature.
Seminary Renovation Project
A second area of focus is the renovation of the Seminário Maior de Nossa Senhora da Conceição, a 16th-century institution adjacent to the Porto Cathedral (Sé). The Diocese of Porto launched construction on this project, with scope including modernization of facilities and, according to reports, a hotel component to generate revenue for the institution.
Residents and heritage organizations have raised questions about whether certain uses are compatible with the character of a classified religious and educational complex in a UNESCO buffer zone. ICOMOS inquired whether the project received proper reviews from Património Cultural, I.P. (the national heritage authority) and the Northern Regional Directorate of Culture (DRCNorte), as required under Portuguese heritage law for interventions affecting classified buildings.
Regulatory Concerns
The incidents highlight questions about enforcement of heritage protection procedures in Porto's historic center. Under Portuguese law, interventions affecting classified heritage buildings require technical review by national or regional heritage authorities before municipal licensing can proceed.
The Porto Municipal Council coordinates heritage licensing with Porto Vivo, SRU (the urban rehabilitation agency) and heritage oversight authorities. ICOMOS has requested the municipality provide technical and administrative documentation on both cases, including permit files and compliance records.
What This Means for Porto Residents
For residents of historic parishes like Ribeira, Sé, and Vitória, enforcement of heritage protection standards directly affects neighborhood character and quality of life:
• Construction impact: Multi-year renovation projects create construction-related disruptions for nearby households and businesses.
• Community character: When historic buildings and traditional businesses are substantially altered or demolished, neighborhoods lose their cultural continuity and local character.
• Heritage preservation: Consistent application of heritage protection rules ensures the city's historic districts retain their authentic character, which is central to Porto's UNESCO recognition.
• Long-term stability: Clear, enforced standards provide certainty for residents and property owners operating in classified zones.
Next Steps
The Porto Municipal Council faces scrutiny to:
Respond to ICOMOS with detailed documentation on the interventions and their compliance with heritage procedures.
Address the Lionesa contraordenação through the established administrative process.
Clarify the Seminary permit process, confirming whether required heritage authority reviews were conducted.
Strengthen enforcement of heritage protection standards going forward.
For developers and property owners in Porto's historic center, the situation underscores that compliance with heritage protection procedures is essential. Transparency in project approvals and early engagement with heritage authorities is now increasingly emphasized as the city faces international scrutiny of its heritage management practices.
