Have you wondered what are the most impressive stained glass windows in the world? The stained glass windows have embellished buildings since the Middle Ages and continue to captivate architects and design lovers today. Traditionally used – and sometimes as roofs, the works are built with colored glass pieces united and outlined by lead strips. It is usual to see these impressive details in religious buildings, such as cathedrals and mosques, although they also popularized for secular spaces from the nineteenth century and now adorn private houses, hotels, cultural buildings and department stores.
