In catholic teachings what is the place where souls go to be punished for sins before going to heaven?

In Catholic teachings, the place where souls go to be purified for their sins before entering heaven is called Purgatory. It is viewed as a temporary state where individuals undergo purification to achieve the holiness necessary to be in God's presence. The Church teaches that prayers and good works by the living can help ease the suffering of those in Purgatory. Ultimately, souls in Purgatory are destined for heaven once their purification is complete.
