The Gran Plaza, officially known as the Macroplaza, is one of the largest public squares in the world — stretching for nearly 800 metres through the heart of Monterrey's city centre. It is flanked by the state government buildings, the cathedral, MARCO museum, and several monuments, connected by formal gardens and plazas at different levels.
The most striking element is the orange Faro del Comercio (Lighthouse of Commerce), a 70-metre concrete tower designed by Luis Barragán that shoots a green laser into the night sky. The square gives a sense of Monterrey's civic ambition and its willingness to think at large scale. It is the natural starting point for exploring the city centre on foot.
