The building diagonally faces the Palacio de la Real Aduana, which houses the Museo Chileno de Arte Precolombino, and Montt Varas Square sits in front.
The building, which is opposite the Ex Congreso Nacional, was built in two phases between 1905 and 1930 in the neoclassical style.
The portico is crowned by a triangular pediment containing the figure of a condor standing on an open book with the word LEX (Latin for law) sculpted over it.
The building has a three-story arcade, which is parallel to the main facade and features a glass skylight.
Ornamental details include caryatids holding bronze swords made by the sculptor Coll y Pi and a stained glass window made in Munich, Germany by Franz Mayer & Co.[1]
