The Bahá'í House of Worship in New Delhi, commonly known as the Lotus Temple, is an architectural marvel renowned for its distinctive lotus flower design. This temple is one of the most visited buildings in the world, celebrated not only for its unique design but also for its use of more than 10.000 sqm of Pentelic marble, known for its pure white color and fine grain, similar to that used in the Parthenon.

The Lotus Temple's structure features 27 free-standing marble-clad "petals" arranged in clusters to form the shape of a blooming lotus. This design not only symbolizes purity and tranquility but also aligns with the Bahá'í faith's emphasis on unity and harmony. The marble used in the construction was provided by Dionyssomarble, sourced from the North Side of the Pentelic Mountains in Greece.

Pentelic marble enhances the temple’s aesthetic appeal, providing a bright, reflective surface that beautifully interacts with natural light. This quality is particularly evident during the day when sunlight illuminates the marble petals, creating a soft, glowing effect that accentuates the temple’s ethereal beauty. At night, strategically placed lighting continues to highlight the temple’s intricate design, making it a stunning landmark against the evening sky.

Inside the Lotus Temple, the use of marble continues to create a serene and meditative environment. The marble surfaces and the open design allow for a tranquil space that encourages contemplation and prayer, in keeping with the Bahá'í tradition of welcoming people of all religions to worship together.

The Bahá'í House of Worship in New Delhi stands as a testament to the harmonious blend of innovative architectural design and the timeless beauty of Pentelic marble, symbolizing the Bahá'í principles of unity, peace, and purity.
