The Palace of Westminster stands proudly as a symbol of British democracy and history. Recognized on the UNESCO World Heritage List, this iconic structure serves as the meeting place for the United Kingdom's Parliament. Although often called the "Mother of All Parliaments," this is somewhat of an exaggeration, but only just. Its present form is mostly a product of the 19th century, following a devastating fire. The building showcases a remarkable example of Victorian neo-Gothic architecture.
Within this grand structure, the House of Commons and House of Lords each have their unique spaces and roles. Located on the northern side, the House of Commons is where elected Members of Parliament (MPs) conduct their business. Its chambers are adorned with green leather upholstery, reflecting its vitality and energy.
On the southern side lies the House of Lords. This chamber is reserved for unelected Lords and boasts an interior of red leather, echoing tradition and authority. Together, these chambers stand as a testament to the UK's rich political heritage and the intricate workings of its government.
