Shortly after Kaliningrad was opened to foreigners in the early 1990s, work began to reconstruct the cathedral. In 1994 a new spire was put in place using a helicopter. In 1995 a new clock was put in place. The clock has four bells (1,180 kg, 700 kg, 500 kg & 200 kg), all cast in 1995. The clock chimes every quarter of an hour. On the hour, the clock chimes by playing the first notes of Beethoven's Symphony No. 5, followed by monotonic chiming to indicate the hour. Between 1996 and 1998, work was done to construct the roof. Work was also done to put in stained glass windows.
