Systrastapi

In 1186 a nun monastery was established in Kirkjubær á Síðu. It was later called Kirkjubæjarklaustur, and the topographical names Systrastapi and Systrafoss are connected to this time. Systrastapi is a steep rocky hill west of Klaustur. 

Folklore says that two nuns of the monastery were buried after being burned at the stake for violating codes of ethics. One is supposed to have sold herself to the Devil, carried consecrated Communion bread past the door of the privy, and had carnal knowledge with men. The other spoke blasphemously of the Pope. After the Reformation, the latter nun was regarded as innocent and beautiful flowers grew on her grave, while the other one's grave remained barren. 

The rocky hill can be climbed, and from the top, the view of glaciers, among other things, is fantastic.
