This weekend in Uruguay is "El Dia Del Patrimonio".
During this celebration, many sites with some historic interest are open to the public for free -- government buildings, museums, churches, and even some private homes. This tradition started in 1995. Every year there is a theme of celebration, this year is TRADICIONES RURALES (rural traditions) and in honor of the poet Bartolome Hidalgo.
