The Praca da Liberdade is Belo Horizontes most elegant square, a grand landscaped space framed by former government palaces now converted into a cluster of museums and cultural centres known as the Circuito Cultural. Palm-lined avenues, gardens and striking architecture, including a building by Oscar Niemeyer, make it a favourite spot for a stroll. The combination of green space and free cultural attractions makes the square one of the citys most rewarding sights.
