For a holiday tradition that is as unique as it is awe-inspiring, make plans to visit the World’s Tallest Glass Tree at Yerkes Observatory in Williams Bay, Wisconsin.
This one-of-a-kind art installation will captivate visitors each year with its beauty, sustainability-focused message, and hands-on opportunities for community involvement.
What is the World’s Tallest Glass Tree?
Standing 36 feet tall, this incredible tree surpasses its counterpart in Murano, Italy, to hold the title of the tallest glass tree in the world.
The tree is constructed entirely from recycled glass bottles collected from Wisconsin and Illinois communities.
Using a mobile glass furnace, the bottles are melted and shaped into molten glass, which is then artistically wrapped around a spinning steel frame.
Visitors have the chance to participate in this process, applying molten glass to the structure and helping bring the masterpiece to life.
The experience culminates in the Star Topping Ceremony, where a hand-blown glass star is placed atop the tree, marking the end of this spectacular creation.
A Celebration of Art, Sustainability, and Community
Yerkes Observatory’s annual event promotes environmental responsibility while celebrating the creativity of artists and tradespeople.
Live glass-blowing and woodworking demonstrations, steel sculpting, and a Winter Market offering handmade crafts and treats will ensure visitors of all ages enjoy the festivities. Proceeds from the event will support community programming at Yerkes Observatory.
The event typically takes place over two weekends in December.
Parking is available at Williams Bay High School, with a heated trolley transporting attendees to the observatory. Tickets can be purchased online or on-site and cost $5 per person, with free entry for children under 9.
