The result was that the medieval street plan survived, however rents rose sharply, forcing the artists elsewhere. They have been replaced by restaurants and bars which draw thousands of tourists. This has been criticised by some for over commercialisation and excessive alcohol consumption. Some of the more historic buildings in the area have been altered in this process, notably St. Michael and John's Roman Catholic Church, one of the city's oldest Catholic churches, which pre-dates the repeal of the Penal Laws and Catholic Emancipation. Its interior was developed to be replaced by a tourist-orientated "Viking adventure centre" which ran into financial problems.
