Berounsko and Příbramsko
One of the more bizarre sights in our neighbourhood is a “pseudo-menhir” that was erected near the village Mořinka on the 31 st of December 1999. Likely due to the momentousness of the date (I believe I previously shared my thoughts about nitpickers who make a big deal over the correct demarcation of decades/centuries/millennia, and I simply do not care), the authors allegedly used the occasion to hide messages for future generations under the rock. A few years later, the menhir was joined by a concrete armchair.
