9. The Johnston Mausoleum, located in Sunnyside, is the largest personal mausoleum in Calvary Cemetery
Calvary Cemetery, the largest cemetery in the U.S., is divided into four main sections: First Cavalry is located within Sunnyside and Maspeth, while Second, Third, and Fourth Cavalry are predominantly located in Woodside. The Johnston Mausoleum, the largest personal mausoleum in the cemetery, is technically located in Sunnyside. The 19th-century mausoleum was built by the Johnston brothers, who operated J.C. Johnston silks and fabrics store on 22nd Street between Broadway and 5th Avenue.
The mausoleum is also the third-tallest building in the cemetery and had cost about $100,000 to construct, or about $2.5 million today. There were only six internments in the mausoleum out of 30 vaults built into the marble. The mausoleum was so pricey that the brothers squandered away the family fortune to build it. The mausoleum has undergone some repairs recently to maintain its historic character.
