San Diego's Hidden Jail Cells

SAN DIEGO'S HIDDEN GEMS

San Diego's Hidden Jail Cells: The Downtown Shopping Center That Used to Be Police Headquarters

Imagine you're walking along San Diego's beautiful downtown waterfront.

The harbor is just steps away.

Restaurants surround a sunny courtyard.

Tourists wander between Seaport Village and the waterfront.

It looks like another beautiful piece of modern San Diego.

But walk inside one particular building and you'll discover something very strange.

Old jail cells.

Real ones.

That's because the stylish complex you're standing inside wasn't originally built for restaurants and shops.

It was once the headquarters of the San Diego Police Department.

Welcome to The Headquarters

Today, the historic complex at 789 West Harbor Drive is known as The Headquarters at Seaport.

It sits directly across from the San Diego Bay waterfront beside Seaport Village.

From the outside, the Spanish and Mediterranean-inspired architecture fits beautifully into Southern California.

Inside are courtyards, restaurants and businesses.

But the name "The Headquarters" isn't clever marketing.

It really was headquarters.

This Was San Diego's Police Headquarters

The building opened in 1939 as San Diego's new central police headquarters.

For decades, this was where a significant part of the city's law enforcement operation was based.

Police officers worked here.

Detectives investigated cases here.

Suspects were brought here.

And people were locked inside cells here.

Which makes today's transformation rather remarkable.

The Architecture Was Designed to Make a Statement

This wasn't built as a plain concrete government box.

The headquarters was designed in a Spanish-influenced architectural style that reflected the image San Diego was developing during the early 20th century.

You'll notice:

Stucco walls
Decorative tile
Arches
Courtyards
Ornamental architectural details

Even when serving as police headquarters, this was meant to be an important civic building.

But Behind the Pretty Architecture Was a Working Jail

This is where the story gets interesting.

The complex wasn't merely offices for police administrators.

It contained detention facilities.

Prisoners passed through these halls.

Jail cells were built directly into the facility.

And unlike many historic buildings that have been completely scrubbed clean of their original purpose...

some of those cells survived.

Yes, You Can Still See the Jail Cells

During the redevelopment of the property, portions of the former police headquarters were deliberately preserved.

Among the most fascinating surviving features are the historic jail cells.

Walk through the complex and suddenly you're standing in front of barred cells that look completely out of place beside modern restaurants and boutiques.

That's exactly why we love them.

Look for the Police Museum Displays

The preserved historic areas include exhibits interpreting the building's law-enforcement history.

Depending on current access and displays, visitors can see artifacts, photographs and information about the San Diego Police Department and the building's former life.

The jail cells are the attention grabber.

But take time to look at the surrounding historical material too.

It helps you understand that this wasn't a movie set.

This was an operating police facility.

Try to Imagine This Area in 1939

This is one of our favorite things to do when exploring historic San Diego.

Forget what surrounds you today.

No modern waterfront development.

No tourist-filled Seaport Village as we know it now.

No giant convention center dominating the waterfront farther south.

San Diego Bay was a working harbor surrounded by military, commercial and industrial activity.

And sitting beside it was the city's new police headquarters.

The Police Department Eventually Moved Out

As San Diego grew, the department eventually needed different facilities.

The old headquarters was ultimately vacated.

And like many large historic civic buildings, its future became uncertain.

Buildings like this are expensive to restore.

They're also tempting redevelopment sites — especially when they're sitting on extremely valuable land beside San Diego Bay.

Instead of Demolishing It, San Diego Reused It

The historic complex eventually underwent a major restoration and adaptive-reuse project.

Rather than erasing the police headquarters, developers incorporated the historic architecture into a new commercial destination.

The property reopened as The Headquarters at Seaport in 2013.

Restaurants and businesses moved into spaces where police operations once took place.

Courtyards became gathering areas.

Historic details were restored.

And the jail cells stayed.

That's What Makes This More Than an Old Building

Cities face this decision constantly.

Tear down the old building and start over?

Or find a way to make it useful again?

The Headquarters is a great example of adaptive reuse.

The building has an entirely different purpose today.

But you can still tell what it used to be.

That's the important part.

The Contrast Is Almost Comical

This may be our favorite part of visiting.

One minute you're deciding where to have lunch.

The next minute you're staring through the bars of an old jail cell.

Then you're back outside beneath palm trees looking toward San Diego Bay.

There aren't many places where a casual waterfront stroll turns into a mini crime-history museum.

Don't Just Photograph the Jail Cell

Look around the building.

Historic details survive throughout the complex.

Pay attention to:

Original architectural elements
Tilework
Arched openings
Interior courtyards
Historic photographs and displays
Police-related artifacts

Once you know the building's history, you'll start noticing clues everywhere.

Nancy's Hidden Gem Tip

Don't Make This a Separate Trip

The Headquarters works best as a surprise discovery during a larger waterfront day.

Visit the USS Midway.

Walk along the Embarcadero.

Explore Seaport Village.

Then walk into The Headquarters and find the old jail cells.

It only takes a little extra time — and suddenly your waterfront afternoon has a completely unexpected history lesson.

You're in One of San Diego's Best Walking Areas

The location makes this Hidden Gem incredibly easy to visit.

Within the surrounding waterfront area you'll find:

Seaport Village
San Diego Bay
USS Midway Museum
Embarcadero Marina Park
The Unconditional Surrender statue
Waterfront Park
San Diego Convention Center
Gaslamp Quarter

You could easily spend an entire day exploring without moving your car.

And There's Another Hidden Gem Nearby

Baseball fans should pay particular attention.

A short distance north along the waterfront is another tiny piece of San Diego history most visitors never notice.

The original home plate location of Lane Field.

Before Petco Park — and before the Padres were even a Major League Baseball team — San Diego's Pacific Coast League Padres played on the waterfront.

The location of home plate is still marked today.

That's another Hidden Gems story we'll be exploring separately.
