National Pantheon of the Heroes, Memorial and church building in downtown Asunción, Paraguay

The white neoclassical structure between Palma and Chile streets contains a mausoleum with remains of presidents and military leaders. Three naves form the interior with side altars and a central dome. Corinthian columns frame the facade while a bronze door marks the entrance to the memorial area where commemorative plaques and military emblems adorn the walls throughout.

In October 1863 President Francisco Solano López ordered a chapel to Our Lady of the Assumption, designed by Italian architect Alejandro Ravizza with builder Giacomo Colombino. The Triple Alliance War (1864-1870) left it unfinished on scaffolding for about seventy years. After the Chaco War, Polish architect Brunon Edward Paprocki directed the completion, and it was inaugurated on 12 October 1936 and decreed the National Pantheon of Heroes.

The Latin inscription 'Fides et Patria' at the entrance reflects the connection between religious faith and national identity in Paraguay. This memorial serves as a central location for state ceremonies and honors the memory of fallen defenders of the nation. Annual commemorations attract numerous citizens who pay respect to the country's founders and military leaders while expressing their patriotic connection.

Multiple guard changes occur daily and offer visitors ceremonial displays. The location serves as the starting point for calculating distances on several major national routes. The building sits centrally and can be reached on foot from various hotels and restaurants in the area. Public transportation serves nearby stops regularly, facilitating access for those arriving from different parts of the city.

The portico's central axis is Paraguay's official kilometre zero: distances on national routes PY01, PY02, PY03, PY04, PY06, PY07, PY08 and PY09 are measured from this point, replacing the earlier reference near Mercado 4. The building was chosen in 2009 as one of the Seven Treasures of Asunción's Material Cultural Heritage. Inside stand statues of Rodríguez de Francia, Carlos Antonio López, Francisco Solano López, Estigarribia, Roque González de Santa Cruz and Bogarín.
