The Dome of Soltaniyeh is a big and important building in Iran. It is very, very old and was built a long, long time ago in the year 1312! It was made by people who lived in Iran a very long time ago, and it is a very special building for the people of Iran.
The building is shaped like a round dome and has really cool patterns and designs on it! These patterns are made with tiles that are very colorful and shiny. Have you ever played with LEGOs before? It is kind of like that, but these tiles are very special and can't be taken apart.
Inside the dome, there are big rooms and hallways where people used to go a long time ago. This building was used as a special place for important people like kings and queens to meet and talk about important things. People also used to come here to pray and do other important things.
Even though it is very old, people still like to visit the Dome of Soltaniyeh today! They can look at the pretty patterns and designs on the outside, and they can even go inside and walk around. It is like taking a trip back in time to when the important people used to come here and talk about important things.
