• Santa began visiting Macy's stores as early as the 1860s, making impromptu appearances at the original Macy's store in New York City.
• By the 1890s, Macy's had formalized Santa's visits by building him a throne in their stores for kids to sit on his lap.
• Macy's Herald Square opened in 1902 and gradually grew into the largest store in the world. Santa's Santaland was established there at some point in the store's history.
• The current Santaland setup at Macy's Herald Square, featuring elaborate decorations, themed areas and activities for kids, has been evolving for decades. It reportedly underwent a major renovation and expansion in 1999.
While I can confirm Santa has had a presence at Macy's for over 150 years, unfortunately I do not have a specific year for when his current Santaland home at Macy's Herald Square first opened. Hopefully this broader context and timeline were helpful! Let me know if you have any other questions.
