The Petcharsk Lava, or Monastery, is a big monastery in the centre of Kiev. It's been a centre of the Orthodox Christian faith ever since this region became Christian in the 10th century AD. These days, Ukraine's security services say that the parish of the Ukrainian Orthodox Church, which runs this monastery, is spreading Russian propaganda. On March 29th, the government ordered the monks in that monastery to leave. Since then, believers have been staging a daily prayer vigil at the gates of the monastery.
