Loussac-Sogn Building
- Also Known As: ANC-359
- Address: 425 D St
The Loussac-Sogn Building in downtown Anchorage is a rare example in the community of the Art Moderne architectural style. Built in 1947 on what was the outskirts of the business district, the professional building was a promise of continuing growth of the town. At the time of its construction it was the largest commercial office building in the community. It is still an impressive and important commercial building in Anchorage, but in the heart not the outskirts of downtown. - NRHP, 14 April 1988
