This castle has existed for centuries.

The 20th century was marked by significant advancements in science and technology.

You can feel his presence.

His existence enriches my life.

This is an important invention of the 20th century.

It's surprising that he can run so fast.

Could you bring me that, whatchamacallit?

What? I couldn't catch what you said.

We are planning to visit the castle this weekend.

This old castle is not used anymore.
