You know how sometimes we go into really old buildings and they look kind of cool and different from the buildings we have today? In Wellington, New Zealand, there are a lot of these old buildings because they used to belong to the government many years ago.
The government is like a big group of people who make important decisions about the country, kind of like a boss for a whole bunch of people. And back when these old government buildings were built, they were used by the people who worked for the government.
Some of these buildings are really big and grand-looking, with huge columns out front and lots of fancy decorations. They might even have secret rooms or hidden passages inside!
Even though they're old and might not be used for the government anymore, people still take care of them because they're an important part of history. Sometimes you can even go inside and look around to see what everything looked like in the past.
So basically, old government buildings in Wellington are like really special and cool buildings that used to be important for the country a long time ago.
