Take a walking tour of the city center, starting at the Customs house, locally known as the Aduana, at Avenida Colon and Paraguayo Independiente. Walk east to the Palacio de Gobierno, a beautiful Versailles-style palace. It was once decreed that if anybody so much as looked at this building they would be shot on sight. Gladly, this rule no longer applies and now the soldiers in front will only shoo you away, except on Sunday when the building is open to the public. Continue east onto Plaza Independencia, where you'll find a 19th-century building that houses the Congresso Nacional. The Cathedral on the far corner is entered from the side street Bogado.
You can catch some of Paraguay's former railway glory at the Railway Museum, Eligio Ayala and Mexico streets (tel. 021/447-848), which is open daily 8am to 5pm and costs G/5,000. If the griminess of the city center gets overwhelming, go northwest on Avenida Ortigas 6km (3 3/4 miles) to the pastoral 250-hectare (618-acre) park Jardín Botánico, Avenida Ortigas and Primer Presidente (tel. 021/281-389). It's open Monday to Friday from 7am to 6pm, Saturday from 7am to 5pm, and Sundays and holidays from 9am to 1pm. It also contains two natural history and indigenous museums. Admission into the park is G/950. One kilometer (about a half mile) south of the park is the beautiful and historical church Santísima Trinidad, Avenida Santísimo Sacramento and Santísima Trinidad. For something more somber, visit the burned-out shell of Ycuá Bolaños Supermarket, Santísima Trinidad and Estigarribia, the scene of a tragic fire in 2004 that killed 700 people. It is now a memorial site.
