Bus Day of Prague Integrated Transport at Letná Plain will once again be a grand showcase of both historical and modern buses, just like last year. On Saturday, May 16, special bus lines — featuring not only historic vehicles — will connect Letná with nearby and more distant parts of the city, offering visitors a unique ride experience. The accompanying program will include booths from PID (Prague Integrated Transport), DPP (Prague Public Transit Company), Czech Railways, and other transport-themed exhibitors.
