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.
