Calle Palma is the main street downtown where several historical buildings, plazas, shops, restaurants and cafés are located. The "Manzana de la Rivera", located in front of the Presidential Palace, is a series of old traditional homes that have been restored and serve as a museum showcasing the architectural evolution of the city. The old railway station maintains the old trains that now are used in tourist trips to the cities of Luque and Areguá. Near Asunción, about thirty minutes outside the city there is also a beautiful lake in the city of San Bernardino. People usually go here during the summer and it is a nice place to visit when the weather is warm.
