Obscura Day 2015 is almost here, with 160+ curious and awe-inspiring events taking place around the world on Saturday, May 30.

Obscura Day is the real-world manifestation of Atlas Obscura – a day of expeditions, back-room tours, unusual access and discovery in your hometown. More than just cataloging the curious, wondrous and overlooked places of the world, we’d like to encourage you to actually go out and explore them. Special events will be taking place at unusual locations across the globe as we highlight obscure collections, eclectic museums, hidden wonders and curiosities near and afar to show that the same sense of wonder invoked by exotic travels can be found close to home if you know where to look.

Here are just some of the Princeton area finds:

Laurence Hutton Collection of Life and Death Masks –  Hutton dedicated his time to collecting these masks and finding the proper historical documentation behind them. Today, this collection belongs to Princeton University and is accessible for research purposes only. This collection contains approximately 100 life and death masks of noteworthy English and American literary and political figures.

Monument to the War of the Worlds – Today visitors can view the spot where the aliens mentioned in the radio show landed. The local community has erected an eight foot high bronze monument to this unique event. Inscribed with a description of the evening and a picture of the alien craft from the story, the monument stands in a quiet location near a pond.

Mercer Museum and Fonthill Castle – There’s just too much to say about this incredible concrete mansion created by Henry Chapman Mercer, a renowned archaeologist, tile maker, and collector of Pennsylvanian pre-industrial household utensils. Just. Go!
