September 7th is Brazil's Independence Day,  Like every year, this day is being celebrated in 2023

This day is celebrated on the completion of 200 years of independence from Portugal

On this day, the preserved heart of Dom Pedro I, the first emperor of Brazil, is put on display

This unique heart of the Emperor is brought by military plane from Portugal every year on 7th September

 After the public display, the emperor's heart is sent back to Portugal,This process has been going on for many years and I don't know how long it will continue
