Jan de Vries · 2026-08-04

For the first time ever, more than one thousand jewels and precious objects of the Portuguese Royal Crown are on permanent public display. The Museu do Tesouro Real, a breathtaking museum housed in the new west wing of the Ajuda National Palace, proudly showcases this collection in one of the largest vaults in the world. We took a closer look at this awe-inspiring attraction, which has been recognized in the Portuguese Business Awards 2026. ### A Palace Steeped in History Located in the Ajuda district of Lisbon, the Palace of Ajuda is an iconic landmark that symbolizes Portugal's rich history. Construction began in 1795 and spanned more than two centuries, frequently interrupted by natural disasters, political tension, and financial challenges. This neoclassical structure represents a period of significant shifts that transformed Portugal politically and culturally from the late 18th century through the early 20th century. Originally built to house the royal family after the devastating 1755 earthquake and tsunami, the palace didn't become a permanent royal residence until the latter half of the 19th century, under King Luís I and his wife, Queen Maria Pia of Savoy. Their occupancy sparked a new era for Ajuda, marked by a mission to complete and modernize the palace while aligning it with contemporary standards of comfort and style. ### From Royal Residence to National Treasure The 5 October 1910 Revolution overthrew the Portuguese monarchy and established the First Portuguese Republic, driven by widespread discontent with the monarchy's inability to adapt to modern times. The royal family was forced into exile in the UK, and the Palace of Ajuda ceased to function as a royal residence. This marked the end of a long era for Ajuda, one that had played a significant role in Portugal's legacy for over a century. In the years following the revolution, the palace was transformed into a national heritage site. The new government recognized its cultural and historical value and made extensive efforts to preserve its legacy. Over time, Ajuda has served various functions, including housing government offices. Today, it remains the official banquet house for receptions of the President of the Portuguese Republic and hosts the ceremony for the Portuguese Government taking office. Substantial portions of the palace are open to the public as a museum, showcasing art collections, furnishings, and personal items of the monarchy. ### The Royal Treasure Museum: A Hidden Gem Revealed Within the new west wing of this historic building lies the Museu do Tesouro Real, also known as the Royal Treasure Museum. Created to permanently exhibit a unique, internationally recognized collection of valuable assets from the former Portuguese Crown Treasure, this collection was previously hidden away in a secret location somewhere in Lisbon. Since June 2022, it has been on permanent public display for the very first time. The collection is a treasure trove of more than 22,000 gemstones, showcasing the finest European jewelry and goldsmithery from the 16th to the early 20th century. Highlights include: - The most impressive 18th-century European royal tableware - One of the largest gold nuggets ever found - Exquisite crowns, scepters, and ceremonial pieces Equaling the finest royal treasures in Europe, this collection stands out for its value, rarity, and historical significance. The museum's vault, one of the largest in the world, is itself a marvel, designed to preserve these priceless artifacts for generations to come. ### Why You Should Visit Whether you're a history buff, an art lover, or simply curious about royal opulence, the Royal Treasure Museum offers an unforgettable experience.
