When modernizing a stadium costs more than building a new one.
While many clubs choose to build new stadiums from scratch, some iconic venues are simply too legendary to demolish. Instead, they undergo massive renovations—often costing hundreds of millions, even billions of dollars. These projects aim to preserve history while bringing stadiums into the future with new technology, better fan experiences, and increased commercial opportunities.
Here are the 5 most expensive stadium renovations ever completed or underway — and the breathtaking upgrades that made them worth the price.
🏟️ 1. Santiago Bernabéu – Madrid, Spain
- 💰 Estimated Cost: €1.3 billion
- 📅 Renovation Completed: 2024
Real Madrid’s legendary home has been reimagined as a multi-purpose, futuristic venue. It now boasts a retractable roof, 360° video scoreboard, a removable pitch system, and a stunning metallic facade. The renovation turned the stadium into a high-tech entertainment complex, ready to host everything from football matches to concerts and corporate events — 365 days a year.
🏟️ 2. Camp Nou (Spotify Camp Nou) – Barcelona, Spain
- 💰 Estimated Cost: €1.6 billion (projected)

Part of the “Espai Barça” project, Camp Nou is undergoing the most expensive stadium renovation in football history. Once complete, it will have over 105,000 seats, full roof coverage, state-of-the-art VIP and hospitality zones, and improved energy efficiency. It’s a massive investment meant to preserve Barça’s legacy while securing its commercial future.
🏟️ 3. Mercedes-Benz Superdome – New Orleans, USA
- 💰 Estimated Cost: $550 million (latest phase)
- 📅 Renovations: Ongoing (2020–2025)
The Superdome, home of the New Orleans Saints, has been modernized through multiple phases since Hurricane Katrina. The most recent upgrades include expanded concourses, premium suites, advanced digital signage, and infrastructure updates to meet the latest NFL and Super Bowl standards. Total renovation costs across all phases are expected to exceed $1 billion.
🏟️ 4. Estadio Azteca – Mexico City, Mexico
- 💰 Estimated Cost: $355 million
- 📅 Renovation Expected: Completed by 2026
As it prepares to host the 2026 FIFA World Cup, the iconic Estadio Azteca — the only stadium to host two World Cup finals — is undergoing a major modernization. The project includes upgraded seating, modernized VIP areas, improved facilities, and a full revamp of the stadium’s surrounding area with new retail and hotel developments. While not the most expensive in this list, it’s a major investment into one of football’s most historic venues.
🏟️ 5. Stadio Olimpico – Rome, Italy
- 💰 Estimated Cost: €350 million (planned)
- 📅 Renovation Target: Before Euro 2032
Set to be a key venue for UEFA Euro 2032, Stadio Olimpico will undergo a deep modernization, including roof expansion, reconfigured seating, enhanced hospitality, and sustainability features. Once complete, the renovation will ensure the stadium meets modern international standards while preserving its Olympic heritage.
These massive stadium renovations show that preserving history can come at a steep price — sometimes more than starting from scratch. But for clubs, cities, and fans, these iconic venues are more than concrete and steel — they’re symbols of identity, legacy, and pride.
And in the age of mega-events and commercial evolution, these upgrades are not just renovations — they’re reinventions.
