Sankt Erikspalatset, Residential tower in Kungsholmen, Stockholm, Sweden.

Sankt Erikspalatset is a prominent residential tower on Sankt Eriksgatan 63 with a reddish facade marked by horizontal bands and limestone details. The building rises approximately 58 meters and displays a distinctive two-part structure that shapes the neighborhood of Kungsholmen.

Sankt Erikspalatset was built between 1907 and 1910 for the manufacturer Gustaf Larsson. The drawings were signed by Dorph & Höög, but the design came from their future partner Gunnar Morssing. The calculated cost of 1.4 million kronor was exceeded by 200,000, and in late autumn 1910 the building stood almost empty, with talk of a forced auction. At 58 metres it was Sweden's tallest building from 1909 to 1924.

The building is blue-classified by the Stockholm City Museum, meaning it has "extremely high cultural-historical values" matching the requirements for listed buildings. Its tower recalls early American skyscrapers, while the facade mixes National Romanticism and Jugendstil, typical of the early 1900s.

The building is easily visible from the street and can be viewed from multiple angles in the surrounding area. Its location in central Kungsholmen makes it a useful landmark when exploring the neighborhood.

The tower's design is credited to Gunnar Morssing, then a future partner of the firm Dorph & Höög, who signed the drawings. The building was intended mainly for flats but also for offices, and the floor below street level was built for industrial use. Its facade toward Kungsholms strand is rough-hewn granite topped by a stone balustrade.
