Can I find any architectural landmarks that are less crowded but still significant?

Absolutely, there are numerous architectural landmarks that offer both significance and a quieter experience away from the usual tourist crowds. One such gem is the stunning St. John the Divine Cathedral in New York City, which is often overshadowed by its more famous counterparts like St. Patrick's Cathedral. This magnificent structure, with its intricate Gothic design and expansive interior, invites visitors to explore its serene atmosphere and unique artwork, including the beautiful Peace Fountain. Despite its grandeur, it tends to attract fewer visitors, allowing for a more contemplative experience.

Another remarkable destination is the National Gallery of Art in Washington, D.C., particularly its East Building, designed by I.M. Pei. This modern architectural marvel features a striking geometric design and houses an impressive collection of contemporary art. While many flock to the West Building for its classic masterpieces, the East Building often remains less crowded, offering a peaceful environment to appreciate both the art and the architecture. The surrounding sculpture garden adds to the charm, providing a lovely space to relax and reflect.

Venturing further afield, the Villa Savoye, located just outside of Paris, is an iconic example of modernist architecture designed by Le Corbusier. This house, often celebrated for its innovative use of space and light, is a UNESCO World Heritage site that sees fewer visitors compared to the bustling attractions in the city center. Its serene location amidst green fields allows for a tranquil visit where you can truly appreciate Le Corbusier's vision and the integration of the structure with its surroundings. Each of these landmarks offers a unique perspective on architectural significance, all while promising a more intimate experience.
