The great Black Plague rock, which has engraved text that can still be seen to a certain extent – it tells future generations about the local pastor who died from the plague, about how the parsonage was established at Sīkrags and then moved to Mazirbe. The rock is also a monument to six pastors of the nearby congregations. All the three stones tell about the horrors of the Black Plague in 1710, the texts have been engraved during the parson Peterson in 1711-1734.
