Prague's Orloj, or Astronomical Clock, is one of the city's major tourist
attractions. But for the next two months some visitors may be disappointed
to find the clock is out of action: it's about to undergo its first repairs
for over a decade. Ludvik Hainz is a well-known Prague clockmaker - indeed,
his family have been taking care of the Astronomical Clock since the 1860s.
I asked him why the work was being done now, not during the winter when
there are fewer tourists.
