Collins Barracks in Dublin is home to the National Museum of Ireland – Decorative Arts & History, one of the four locations of the national museum. Located in an imposing 18th-century barracks, the complex is one of the largest historical buildings in the city and offers a fascinating journey through Ireland's military, social, and artistic history.

The permanent collection includes uniforms, weapons, medals, silverware, ceramics, furniture, and clocks, telling the story of the evolution of design and daily life from the 17th century to today. Particularly interesting is the section dedicated to the 1916 Rising and Irish independence, with artifacts and historical documents that trace the nation's most significant moments.

In addition to decorative art objects, the museum offers exhibitions on social and cultural themes, such as Irish fashion, industrial design, and craftsmanship. The building itself, with its inner courtyards and monumental architecture, is worth a visit for its history and the unique view it offers of the city.

Admission is free, and the museum organizes temporary exhibitions, guided tours, and educational activities for families and students, making Collins Barracks a must-visit stop for those exploring Dublin.
