Blenheim Palace, one of Britain's most cherished landmarks and a UNESCO World Heritage Site, is embarking on a monumental £10.4 million restoration project focused on critical repairs to the palace roof.

Set to begin in January 2025, this ambitious restoration aims to preserve the architectural grandeur of "Britain's Greatest Palace" for future generations. As part of the initiative, visitors will gain unprecedented access to previously unseen areas of the palace and estate through three unique experiences set to launch in the spring.

The project centres on restoring a significant section of the palace's vast roof, addressing long-standing water damage, structural wear, and age-related decay. The repairs will be carried out by DBR Ltd, specialists in historic building conservation, who will work to maintain the authenticity of Blenheim’s 18th-century architecture. The palace roof—spanning almost an acre—has suffered severe deterioration, including water damage impacting priceless artwork and swelling iron cramps that threaten the stonework. The Great Hall, former servants' quarters, and Saloon have been particularly affected, with waterlogged timbers and the presence of Death Watch beetles compromising structural stability.


The damages have endangered some of Blenheim's most valued artworks, including Sir James Thornhill’s ceiling fresco in the Great Hall, which depicts the Duke of Marlborough kneeling before Britannia. Conservation efforts will also address damp, mold, and smoke damage affecting Louis Laguerre's famed "Battle of Blenheim" painting. The roof project will focus on creating a watertight seal, increasing rainwater capacity, and completing fire compartmentation work to better protect the palace’s historic interior and artifacts.

As Blenheim Palace undertakes these extensive restorations, visitors will have new opportunities to explore unique areas of the estate, including:

Roof Top View: A newly installed ticketed viewing platform will offer a panoramic view of the estate and Oxfordshire countryside, including the iconic Column of Victory. This elevated vantage point will provide visitors with a one-of-a-kind experience of Blenheim from above.

Life Below Stairs: This immersive experience will give visitors a glimpse into the daily life of Blenheim’s servants, exploring the original palace kitchens and historical quarters. Through sights and sounds recreating the late 19th-century work environment, guests will learn about the kitchen staff, household team, and gardeners who served the Marlborough family.

Family Treasures: For the first time, guests can step into private apartments within the palace, including grand State Rooms filled with rare artifacts and historical treasures. Highlights include George Stubbs’ portrait of a tigress, a rare Benjamin Vulliamy clock from 1787, and the Grand Cabinet’s collection of family portraits. This tour allows visitors to trace the footsteps of dukes, duchesses, and esteemed guests through some of Blenheim’s most opulent rooms.

Additionally, Blenheim's renowned gardens will undergo seasonal transformations throughout 2025, offering new features and experiences for visitors.

The Blenheim Palace roof restoration, planned in stages to minimise visitor disruption, represents a vital investment in preserving the historic estate amid challenges posed by age, climate change, and rainfall. With this project, Blenheim Palace continues to safeguard its heritage, inviting guests to explore its history and hidden gems in fresh and unprecedented ways.
