He was popular among the farmers in the area, offering them aid and refuge within the castle walls when enemies approached.
In his moments of leisure, Floris loved falconry, which is hunting with birds of prey. Sadly this did not end well, while on a hunt in 1296, his ‘friends’ capture him and lock him up in his own castle. Farmers from the surrounding area wanted to free him but failed. Shortly thereafter Floris was brutally murdered near the castle. Little was left of Muiderslot castle after that, as Floris V’s enemies destroyed almost all of it. It was not until 1370 that the castle was rebuilt and even expanded.
