Inside the Pergamon Museum’s Massive Renovation: Secrets, Challenges, and the Future of Berlin’s Iconic Landmark

Berlin’s Iconic Pergamon Museum Set to Re‑Open Its North Wing and Legendary Altar Hall in Early 2027

After a three‑year closure for a €500 million first‑phase overhaul, teh UNESCO‑listed museum on Berlin’s Museum Island will once again welcome visitors to the world‑renowned Pergamon Altar – a highlight of a multiyear renovation that will stretch to 2043.

BERLIN – The Pergamon Museum, one of Berlin’s “must‑see” attractions and a cornerstone of the UNESCO‑listed Museum island, will unveil its north wing and the monumental Pergamon Altar hall to the public in early 2027. The declaration follows a press preview on December 4 that gave journalists a rare glimpse of the museum’s massive restoration work, which began in October 2023 and is expected to continue for another two decades.

“This is a treasure of humanity,” said Wolfram Weimer, the federal commissioner for culture and the media, during the presentation. “We’re not expecting hundreds of thousands of visitors in the coming years; we’re expecting millions, because it’s designed as a location of global meaning.”

A Century‑Old Building Gets a 21st‑Century Makeover

Commissioned by kaiser Wilhelm II and constructed between 1910 and 1930 according to architect Alfred Messel’s plans, the Pergamon Museum has survived world‑II bombings, post‑war neglect in East Germany, and decades of wear. The current renovation respects the historic fabric – preserving original windows,façade details and even visible traces of wartime damage – while upgrading lighting,climate control and security systems to meet modern conservation standards.

Key upgrades include:

* Enhanced climate and lighting to protect millennia‑old sculptures and reliefs.
* Full accessibility for visitors with disabilities, a first for the historic building.
* A new glass‑roof structure over the Pergamon Altar hall that floods the space with natural light while safeguarding the ancient stonework.

Engineering Challenges Beneath the Spree

The museum sits on a sandy,unstable substrate next to the Spree River. to stabilise the foundation, engineers installed more than 700 high‑strength steel micropiles that reach 10‑30 metres underground. While drilling, workers uncovered two forgotten pumping stations from the museum’s original construction – relics that had been buried without documentation, prompting an unplanned technical step and inflating costs.

The first phase of the project has already ballooned to nearly €500 million (about $580 million), double the original estimate. The entire renovation, slated to finish between 2037 and 2043, is projected to cost ≈ €1.5 billion.

What Will Visitors See in 2027?

The centerpiece of the early‑2027 reopening is the Pergamon Altar, an exquisite 2nd‑century BC Greek temple façade excavated by Carl Humann in the 1870s. The altar’s dramatic high‑relief frieze depicting the battle between the Giants and the Olympian gods has long been hailed as one of the “Seven Wonders of the Ancient World.”

During the refurbishment, the altar remained in situ, encased in custom‑built protective shells of padding, wood and metal brackets. The new glass ceiling and roof not only improve visitor sightlines but also create a luminous atmosphere that highlights the altar’s intricate carvings.

“It’s quite exceptional to build and renovate a building amid its existing collection,” Weimer added, underscoring the logistical complexity of working around the priceless artifacts.

timeline and Visitor Outlook

* 2024‑2026 – Ongoing structural reinforcement, façade restoration, and installation of modern HVAC and lighting systems.
* Early 2027 – Public reopening of the north wing and Pergamon Altar hall.
* 2027‑2043 – Sequential refurbishment of the museum’s remaining wings, including the islamic Art and Near Eastern collections, with staggered temporary closures.

Cultural officials anticipate a surge in tourism once the altar hall reopens, forecasting millions of visitors over the next decade. The museum’s management plans to complement the physical reopening with digital tours and educational programs aimed at a global audience.

Why It Matters

the pergamon Museum’s revival is more than a construction story; it is indeed a testament to Berlin’s commitment to preserving cultural heritage while adapting to contemporary standards. By safeguarding one of humanity’s moast celebrated ancient monuments and ensuring its accessibility for future generations, the project reinforces Museum Island’s status as a UNESCO World Heritage site and a beacon for art lovers worldwide.

The first tickets for the 2027 reopening are expected to go on sale later this year. stay tuned for the exact date and price details.
