The manhole covers in Tabor show the city arms. The coat of arms dates back to 1437. In this year, Sigismund of Luxembourg granted these arms to Tabor. At that time, there was a Luxembourgian lion part of the arms. The Bohemian lion replaced it in the 16th century.
While walking through the Czech city Tabor I came across this funny fireplug. Tabor is a historic city in the region of South Bohemia, Czech Republic. An attraction of this place is an accessible system of tunnels below the city.
