However, the configuration of the 45 major bridges in Bristol is such that an Eulerian circuit exists. [15] This cycle has been popularized by a book [15] and news coverage [16] [17] and has featured in different charity events. [18] Comparison of the graphs of the Seven bridges of Konigsberg (top) and Five room puzzle (bottom). The numbers ...
Seven Bridges of Königsberg – Walk through a city while crossing each of seven bridges exactly once. [6] Squaring the circle, the impossible problem of constructing a square with the same area as a given circle, using only a compass and straightedge. [7]
That is, we proceed as if a solution exists and discover some properties of all solutions. These put us in an impossible situation and thus we have to conclude that we were wrong—there is no solution after all. [3] Imagine that there is an "observer" in each "room". The observer can see the solution line when it is in his room, but not otherwise.
The Bristol Bridges Walk is a circular hiking route that is linked to the Königsberg bridge problem, a mathematical puzzle, which laid the foundation for graph theory, the mathematical study of networks. [2] [3] [4] The Bristol Bridges Walk presents a solution of the puzzle for the city of Bristol. [5]
Multigraphs of both Königsberg Bridges and Five room puzzles have more than two odd vertices (in orange), thus are not Eulerian and hence the puzzles have no solutions. Every vertex of this graph has an even degree. Therefore, this is an Eulerian graph. Following the edges in alphabetical order gives an Eulerian circuit/cycle.

The bridge problem inspired the Bristol Bridges Walk. Like Konigsberg Bristol spans the two banks of a river and two river islands. The Bristol Bridges walk is an Eulerian cycle crossing all 45 major bridges in the city. It has been the subject of the several articles in newspapers and magazines, and there is a book about the walk.
