Nothing equals the delicate beauty of a Central Asian madrasa. Those religious buildings, that served as schools and had a strong influence in the 11th to 14th centuries, are fascinating attractions.
They fill the tourists with wonder, with their deep blue colours that blend into the sky.
They inspire the photographers, with their meticulous geometrical patterns.
They are worthy of all of our admiration, with their stunning overall beauty as much as their unrivalled attention to detail.
Let me take you on a little voyage in mosques and madrasas; from Iran, where it all started, to the awe-inspiring madrasas of Central Asia.
