Mary Baker Eddy Library

The Mary Baker Eddy Library is a research center and museum in Boston's Christian Science Center that focuses on religious history and faith traditions. The building houses collections of Bibles and religious documents along with the distinctive Mapparium, a walk-through glass structure.

The institution was founded in 2002 to preserve materials related to Mary Baker Eddy and the development of Christian Science as a religious movement. The collection documents how religious journalism and publication shaped the growth of faith communities.

The library displays rare religious texts and manuscripts that reveal how faith and belief have been documented across time. Visitors can explore historical volumes that show different traditions and how sacred writings shaped communities.

The reading room is open on several weekdays and visitors can view research materials without advance booking. It is helpful to check which materials are available in advance and when is the best time to plan a visit.

The Mapparium is a walk-through glass globe with hundreds of colored glass panels showing the world as it appeared in the 1930s. Viewing the map from the inside creates an unusual perspective that often surprises visitors.
