Viking Altar Rock, Archaeological site in Sauk Centre, Minnesota, United States.
Viking Altar Rock is a large glacial boulder located in Sauk Centre with four triangular holes positioned roughly one meter above its base. The stone sits in an open area where visitors can walk around it and examine the carved indentations from multiple angles.
The boulder was first documented in 1943 as part of regional geological surveys. Its holes resemble those that local farmers carved into rocks during the late 1800s, though its Norse name reflects local speculation about earlier visitors.
The site forms part of the Trail of Vikings, a collection of locations suggesting potential Norse exploration throughout Minnesota's historical landscape.
The site is located in an open area marked with signage, making it easy to find and access on foot. Wear comfortable shoes because the ground around the boulder is uneven and can become slippery after rain.
In August 1975, the boulder received special recognition through an ecumenical Mass celebration that marked its rededication ceremony.

Minnesota contains numerous locations away from the main tourist circuits. The state stretches from the shores of Lake Superior to the southern prairies, encompassing historic lighthouses, underground mines, waterfalls, and Japanese gardens. Visitors find both natural landscapes and cultural sites that tell the story of the region's history. Notable locations include prehistoric rock carvings at Jeffers Petroglyphs Site, where indigenous peoples left their marks thousands of years ago, and sacred trees of Ojibwe culture. The geological formation known as Devil's Kettle, a waterfall whose course puzzled scientists for years, attracts visitors interested in natural phenomena. Historic mines provide insight into Minnesota's industrial past, while lighthouses recall the maritime history along the largest of the Great Lakes.
