Sky Bridge 721 is a suspension footbridge in the municipality of Dolní Morava, Czech Republic.

It was the longest of its kind in the world[1] till the Bridge of National Unity in Hungary was opened.

[2] Located in the Králický Sněžník mountain, it offers users panoramic views of the landscape.

An "educational nature trail" called "The Bridge of Time" was prepared with elements of augmented reality in cooperation with the state-owned enterprise Lesy ČR (Forests of the Czech Republic)[3] and the Museum of Czechoslovak Fortifications of 1935–1938.

[4] A game with ten educational panels covers the topics of environmental protection and how to behave in the countryside, as well as the history and life story of a family from Dolní Morava against the backdrop of events that affected Czechoslovakia / the Czech Republic from 1935 until now.
