Cusco Cathedral, a masterpiece of Spanish colonial architecture, is perched magnificently on the Plaza de Armas. This grand edifice, completed in the mid-17th century, boasts a stunning façade of red granite blocks, sourced from the ancient Incan site of Sacsayhuamán. Inside, the cathedral houses an impressive collection of colonial art and artefacts, including an exquisite carved wooden altar and the impossibly intricate silver-plated Main Altar. A curious gem within its walls is a painting of The Last Supper, uniquely featuring indigenous foods such as guinea pig. This historic treasure is not only a spiritual centre but also a symbol of Cusco's rich cultural tapestry.
