@Hadithoftheday Jannah.
Jannah (Paradise/Heaven) has eight gates while as Jahannam (Hell) has seven gates.

4.Bab-Ar-Rayyan
5.Bab-al-kazimeen-al-ghaiz-wal-aafina-anin-naas
6.Bab-al-hajj
7.bab-al-iman
8.bab-al-dhikr
Each gate has a name describing the kinds of people who will enter through these

Seven gates or levels of Hell/Jahannam are:
1. Jahannam
2. Ladha'
3. Saqar
4. Al-Hutamah
5. Jaheem
6. Sa'eer
7. Al-Haawiyah

Allah mentions seven gates of Hell in Surah Hijr of Glorious Qur'an.

Allah says in Qur'an:
"And indeed, Hell is the promised place for them all."
"It has seven gates; for every gate is of them a portion designated."
(Qur'an :Al-Hijr 15: Verse 43,44)

Each level of Jahannam not only contains different temperature, but also have different punishments and also contain different people.
The gates of Hell are structured one gate below the other descending.
