A photographic celebration of beautiful windows from across the globe and their allure as portals between inner and outer worlds. Swedish photographer Marcus Cederberg is globally renowned for his eye-catching, minimalist images. His iconic images of windows have attracted hundreds of thousands of fans on social media. In his work, a window is never just a rectangle on a wall: it becomes a character, a punctuation mark, or even a metaphor for what lies beyond. Through repetition, symmetry, and the subtle tension of imperfection, Marcus creates photographs that invite viewers to pause, reflect, and imagine. Here are nearly 200 of his most beloved images, from Portugal to New York to the Bahamas.
