Les Halles Saint-Géry is a place with lots of history and is worth visiting if you're in Brussels. The Gothic church of Saint-Gery stood here until its demolition between 1798 and 1801 during the French regime. On its site, a pyramid-shaped fountain was built in 1802, and markets were organised outdoors. In 1881 the construction of the Les Halles market started, which remained active until 1977 when it was closed after years of gradual abandonment by the shopkeepers. The building is a fine example of the architecture of the period. It's a covered market in iron and red brick done in the Flemish Neo-Renaissance style. Today, fully restored, it's a hub of information and exhibits and also houses a coffee shop with an intense and interesting schedule of events, the Café des Halles. There's a great atmosphere here, as it's always full of young people from Belgium and beyond. The exhibitions can be visited from 10:00 to 18:00 and admission is free.
This secluded and beautiful place is also called the Old Market Square. It has retained the same appearance since the 18th century. It's where many of the city's residents come to have a drink or a coffee in the sun. It also houses one of the most popular churches of the old town, the Church of San Juan Bautista. Sadly though, there has not been a lot of reconstruction or preservation of the temples of the country.
