In part 2 about the borough of Manhattan, Sigrid completes her overview of all 5 boroughs of New York City. She talks about some nicknames for New York City, including "the Big Apple."

We've finally made it to Manhattan, the smallest but most densely populated borough. When we think of New York City, Manhattan is more often than not what comes to mind. This is part 1.

It's time to have a look at Staten Island, the 4th borough out of 5. It looks closer to New Jersey than to the rest of New York City and has some other peculiarities.

To get from eastern Long Island to the city, travelers and commuters have to go through Queens, so this borough naturally became a very important transit hub, with Jamaica at its center. It also became crisscrossed with many expressways for vehicles.

Having explored the Bronx and Brooklyn, Sigrid now tells us all about Queens, which is geographically speaking the largest of the 5 boroughs of New York City.

Sigrid talks about the different ways to get from Brooklyn to Manhattan, and about some of the characteristics of this borough. For one thing, it is more affordable than Manhattan, although by no means a cheap place to live.

In the first of two parts, we look at Brooklyn's beginnings and how it came to be one of New York City's boroughs.

The borough of the Bronx has gotten a bad name because of issues with poverty and crime. It's also had its share of neglect and mishandling on the part of local and state administrations. However, the Bronx also has some claims to fame, such as the Bronx zoo and botanical garden.

The Bronx was the first area to become part of New York City. Lying to the north and northeast of Manhattan, it was a logical addition. The quirky name of this borough has its own history.

Sigrid seeks to answer the question "What's a borough?" In doing so, she talks about how New York City got its start, and also about the surrounding counties that played an important role in its development. In this video, you'll see 18th- and 19th-century maps of the area.

Sigrid describes the first part of her trip from Long Island to New Jersey, taking a moment to tell us about the famous Verrazzano Narrows Bridge.
