Ivančena, Stone memorial at Lysá hora mountain, Czech Republic.

Ivančena is a stone cairn about 4 metres tall and 10 metres long, raised beside the summit of Lysá hora between Malchor and Kykulka. It began as a simple cross set on a pile of stones by the 30th Scout section of Moravian Ostrava in 1946, and grew stone by stone as visitors added to it. It was moved a few metres off the ridge in the 1990s and rebuilt in 2017.

The memorial was erected in October 1946 to honor five members of the Silesian Scout movement who were executed by the Gestapo in 1945. These individuals had resisted the occupation.

The name Ivančena comes from Ivanka, the site's original owner. Pilgrimages continue each year on the last Saturday before or on Saint George's Day, 24 April, with Scouts arriving one day and trampers the next. Since 1996 a memorial event has also been held at the Jewish cemetery in Cieszyn, Poland.

The cairn sits below the summit of Lysá hora between Malchor and Kykulka, in the Malenovice cadastre; access is on foot along marked trails from the surrounding Beskid villages. The traditional ascents fall on the last Saturday on or before 24 April, when Scouts walk up, followed by trampers the next day. The mound was moved a few metres off the ridge during its reconstruction so that it would not sit on the boundary of three municipalities.

The cairn keeps growing as visitors add stones, and it now holds rocks from around the world. The mound stands about 4 metres tall and 10 metres long, and in December 1994 vandals smashed several of its memorial plaques, prompting a reconstruction led by Pavel Ženatý.
