Abstract

Archcathedral Yura in Lviv - Cathedral of the Metropolitan of Halychyna of the UGCC, a Baroque-Rococo monumental architectural ensemble with expressiveness of the National Actress, is considered to be the main shrine of the Ukrainian Greek Catholic. Located on Svyatoyursky Mountain, at: St. Yura's Square, 5. Since 1998, the cathedral itself is part of the complex: the Baroque Cathedral from the bell tower, the Rococo Metropolitan Chamber, the Chapter House, the terrace from the two-step staircase, the openwork fence around the courtyard courtyard in the courtyards and the ants that trim the capitals and the power garden. Around 1762-1771, a decorative garden was laid out around the metropolitan palace on terraces supported by strong retaining walls.

Since 1996, a large-scale interior renovation of the temple has been carried out. Together with the historical center, the Lviv Cathedral Complex was included in the UNESCO World Heritage List  in 1998

In 2018, UAH 20 million was allocated from the state budget for reconstruction to: replace the systems of engineering communications, landscaping, restoration of stone and metal fences; streamlining of yard area that eliminates the emergency state of northern and central entrance gates. At present hours are ongoing work on the arrangement of the north bypass, in particular, removal of the emergency state of the northern part of the retaining wall of the Baroque Gardens.

Based on the results of the inspection of the main load-bearing structures of the retaining wall, it can be concluded that the condition of the structure as a whole is emergency and it can be operated only after its reconstruction with reinforcement of individual elements and restoration. For this purpose, a reconstruction project was prepared taking into account the existing condition of its main structural parts and the projected loads on them.
