Ramundeboda kloster, Medieval abbey ruins in Laxå Municipality, Sweden.

Ramundeboda monastery is a medieval religious site in Laxå Municipality with stone walls and building foundations still visible from the original structures. The ruins reveal the basic layout of how the complex once functioned, with several distinct areas that separate the different activities that took place here.

Ramundeboda was already a resting place on the Eriksgata royal route in the 12th century. The Antonine convent is documented between 1475 and 1530, and in 1527 Gustav Vasa confiscated its assets to the crown. The site then served as an inn until the mid-19th century.

The name Ramundeboda is pronounced with stress on the second syllable. The site lies on the Munkastigen trail, which led past the monastery toward Olshammar and on via Lake Vättern to houses such as Vadstena. The Antonine order that ran it focused on healthcare and gave food and lodging to pilgrims and travellers.

The ruins lie beside a large rest area on the E20, and excavations and restorations since 2007 aim to make them easier to reach. The double cellar was restored in 2008–2010, when a previously unknown window opening and 16th–17th-century coins were found. Parts dug in 1910–1912 were later refilled, so the ground is uneven.

The 1910–1912 excavation found coins from the late Middle Ages and from every Swedish king from Gustav Vasa to Karl XII, showing the site stayed in use long after the monastery closed. The area around the double cellar was backfilled, and it is unclear whether this happened during the excavation or later.
