  3. Aimsoftheproject: • Survey and diagnosis of existing timber structures

  4. Aimsoftheproject: • Testing of timber properties • Correlation relationships between destructive and semidestruktive methods

  5. Želiv monastery

  6. History of Želiv monastery • Premonstratensian monastic complex with st. Mary’s birth church in Želiv is national historic landmark. • Foudation of monastic complex is dated to the early 12th century. • After fire in 1681 building of convent was restored under guidance of architect Giacoma Antonia de Maggi. • From 1710 Antoni Scotti was worked in monastery and later ingenious Jan Blazej Santini – Aichel. • At the beginning of 20th century the monastery fired. • In 1993 the religious life came back to monastery and renew is in progression.
