Hello, I'm Marc C.

I am a natural-born explorer who has worn many hats: pilot​,​ global traveller​,​ entrepreneur​,​ and an official Guinness World Records Adjudicator. As part of my work with Guinness World Records​,​ I have witnessed and verified some of humanity’s most extraordinary achievements​,​ and have had the rare privilege of standing alongside those who have made history. Years of measuring the world’s most remarkable achievements and exploring different cultures have shaped the way I see the world. I have learned that extraordinary stories are everywhere - often hidden in the details of everyday places​,​ waiting to be uncovered by those curious enough to look closer. I bring this same passion for discovery to my walking tours. I treat the city like a living museum​,​ guiding guests through hidden layers of history​,​ local stories​,​ and fascinating urban secrets that standard guidebooks often miss. When you explore with me​,​ you won’t just learn about a city - you’ll experience it through the eyes of someone who has spent a lifetime searching for remarkable stories. Together​,​ we’ll uncover the forgotten details​,​ surprising connections​,​ and hidden moments that make a place truly come alive.
