<P> The BBC had been developing the idea of a new series based on The Three Musketeers since as far back as 2007, when the project was envisaged as a Saturday evening show to run between series of Doctor Who . The eventual production of the series was finally announced in 2012, with Adrian Hodges in charge of the project . </P> <P> Paris was not considered as a filming location because over the decades, development had detracted from the grittier architecture wanted . Dublin was also considered before settling on the Czech Republic, which suffered little damage during the two world wars . Many historic buildings were intact and privately owned stately homes were rented for filming . </P> <P> Filming for the series took place mainly in Doksany, 30 kilometres north - west of Prague, where a Parisian square, a number of streets and the musketeers garrison were constructed . A disused convent had additional sets constructed including taverns, bedrooms and mortuary . </P> <P> During filming of the first series Peter Capaldi learned that he had been given the role of the Twelfth Doctor in Doctor Who . The show's executive producer Jessica Pope commented that they would have to "recalibrate" plans for a prospective second series, in order to accommodate Capaldi now being unable to reprise his role . Marc Warren joined the cast for the second series . The Musketeers was originally planned to be broadcast in 2013, but was later delayed until 2014 . </P>
