BBCs Sherlock, starring Benedict Cumberbatch and Martin Freeman, has become a worldwide sensation since the first series aired in July 2010.
The show is mostly filmed in London and Cardiff, both on location and in a studio. The exterior filming of Sherlock and John’s shared flat is 187 North Gower Street, standing in for 221b Baker Street. This is also the location of Speedy’s Cafe, which can be seen in the TV series.
