Frederick Ayer Mansion

The Frederick Ayer Mansion at 395 Commonwealth Avenue is a residential townhouse built in 1900 with intricate mosaic designs and architectural elements created by Louis Comfort Tiffany in collaboration with Alfred Manning. The building showcases both exterior and interior craftsmanship that demonstrates the artistic ambitions of the Gilded Age era.

The mansion was built in 1900 for entrepreneur Frederick Ayer and represents the wealthy residential development of Boston's Back Bay neighborhood in the late 1800s. It arose during an era when successful industrialists commissioned grand residences with renowned artists and craftsmen.

The house displays Moorish and Byzantine influences through its stone mosaics, stained glass windows, and ornate interior decorations that reflect the artistic tastes of wealthy Back Bay residents.

The building is currently a private residence operated as student housing by the Trimount Foundation and is not typically open for tours. Plan to view the property from the street to appreciate the mosaic and window details from the Commonwealth Avenue sidewalk.

The mansion holds the only surviving exterior stone mosaics designed by Tiffany for a residential building in the United States, making it a rare and significant remnant of his artistic workshop. These mosaics represent a precious example of high-level collaboration between a world-renowned glass artist and local craftspeople.
