The Chase Mansion is located in the Back Bay Neighborhood of Boston, Massachusetts. The House is located on Commonwealth Avenue, and the back is on public alley 429.


The mansion was owned by Randolph Chase, and was presumably owned by his father before him. His sister Natalie, and brother Frederick lived here in their youth. 

After one thanksgiving, Randolph's siblings and their children never visited the mansion again for eleven years. 

The mansion is currently owned by Annabeth Chase (jointly with Magnus Chase).

Magnus Chase and the Gods of Asgard  

The Sword of Summer  

Magnus sneaks in to the family mansion to find answers as to why he is in danger and learns the truth from Randolph. Magnus could easily understand why his mother had never liked living there, and why she had become a fan of the great outdoors. According to him the mansion was dark oppressive and creepy.

The Hammer of Thor

Magnus and Alex sneak into the mansion to find information on Mjolnir. They find a picture of Bridal veil Falls and theorize that the wedding is there.

The Ship of the Dead
