Stand on Sepah Street in the late afternoon and the layers of Qazvin stack up around you: a Safavid capital's main axis, the first street laid out in Iran, with the bazaar closing in on one side and the Alborz rising cold and dry to the north. This is a city of caravanserais, calligraphy and confectionery, an easy run northwest of Tehran and a practical base for the mountains.
It suits travellers who want a working Iranian provincial capital rather than a museum piece, and who are willing to use Qazvin as a springboard for the Alamut valley. Most of the urban sights sit within walking distance of each other in the centre.
This guide covers the sights and experiences the sources describe, ordered from the ones worth building a trip around down to the ones you can fold into an afternoon.
Top things to do in Qazvin
1. Alamut Castle
From Qazvin you can make a day trip into the mountains of Alborz to see the remains of Hasan-e-Sabah's castle at Alamut, from where he ruled the assassins order. The castle was reconstructed around 2013 in a way that may seem questionable from an archaeological point of view, and it is a UNESCO World Heritage Site.
Treat this as a full day out rather than a city sight, and combine it with the hiking and trekking the surrounding valley offers. If you want to see the mountains from the air instead, paragliding is available at the blue sky flight site in Shafi Abad and along Barajin Road near Fadak Park, where you can ask a local agent such as Irantaste.
2. Sa'd al-Saltaneh Caravanserai
Built during the Qajar era, this is one of the preserved urban caravanserais in Iran. It sits within the Sad-o-saltaneh complex, which makes it the natural anchor for a walk through the bazaars.
Pair it with a break at Negarossaltaneh Café on Rasteh Vazeer inside the same complex, and give yourself time simply to wander the bazaar lanes around it.
3. Jameh Mosque of Qazvin
One of the oldest mosques in Iran and the grand congregational mosque of the city, its foundation laid on a Zoroastrian fire temple. The dome chamber is the oldest known structure in Qazvin that still exists, and the present-day building is one of the largest mosques in Iran.
It is a short walk from the bazaar area, so combine the two in a single morning while the light in the courtyard is still low.
4. Ali Qapu mansion
Qazvin holds few buildings from the Safavid era, when it was capital of Persia, and perhaps the most famous of the survivors is the Ali Qapu mansion, today a museum in central Qazvin. It is the clearest way to see the city's capital period in built form.
Because it is central, it works well as a stop between the bazaar and Sepah Street rather than as a separate outing.
5. Qazvin Museum
The city museum is the place to put the archaeological background in order before or after you walk the old centre. Qazvin's plain has revealed urban agricultural settlements going back nine millennia, and there are several archaeological excavations in the area dating back 9000 years.
Visit it early in your stay so the rest of the city has context, then continue on foot to the nearby central sights.
6. Sepah Street
Sepah Street is the first street built in Iran, and walking it is one of the simplest pleasures in the city. It runs through the historic core, close to the bazaar and the caravanserai.
Walk it in the late afternoon, when the heat has gone off the day, and use it to link the bazaar, the caravanserai and the central mansions into one route.
7. Al-Nabi Mosque
Also known as the Soltani Mosque, this massive mosque was built in 1787, with some parts dating back to the Safavid dynasty era. Its scale makes it one of the more imposing stops in the centre.
Combine it with the Jameh Mosque in the same walk, since the two together give you the range of the city's mosque architecture.
8. Tomb of Hamdallah Mustawfi
A 14th century mausoleum, and one of the more quietly rewarding monuments in Qazvin. It rewards a short, unhurried visit rather than a slot in a rushed itinerary.
Fit it into the same day as the other historic monuments rather than making a special trip for it alone.
9. Aminiha Hosseiniyeh
A historic house of mourning in the old city, listed among the places worth visiting in Qazvin. It is one of the traditional buildings that give the centre its texture.
Include it in a walking loop of the old streets rather than treating it as a standalone destination.
10. Qajar Hamam
The Qajar-era bathhouse is one of the city's historic buildings open to visitors. It is a good example of the everyday architecture that survives alongside the mosques and mansions.
Pair it with the nearby bazaar and caravanserai, since all three sit in the same historic fabric.
11. Russian Church of Qazvin
Qazvin contains three buildings put up by Russians in the late 19th and early 20th century: the current Mayor's office, formerly a ballet hall, a water reservoir, and the Cantor church, where a Russian pilot is buried. The church, also referred to as Kantour Church, is the most visitable of them.
It sits slightly apart from the mosque-and-bazaar circuit, so slot it into a separate short walk.
12. Chehel Sotoun
Chehel Sotoun is among the sights listed for Qazvin, another remnant of the city's historic building stock. It is worth adding if you are working through the central monuments systematically.
Group it with the other central sights on the same walking day.
13. Meimoon Ghal'eh
In the middle of the city lie the ruins of Meimoon Ghal'eh, one of several Sassanid edifices in the area. It is a fragment rather than a reconstruction, which is part of its interest.
Visit it as a short stop while crossing the city, not as the focus of an afternoon.
14. Wander the bazaars
Wandering in the bazaars is one of the defining things to do in Qazvin, and the city is known for its traditional confectioneries, such as Baghlava, and for its carpet patterns. This is where you see the working city rather than the monument trail.
Go with no fixed route, and break the walk at Negarossaltaneh Café in the Sad-o-saltaneh complex when you need to sit down.
15. Ovan Lake
Swimming at Ovan Lake is about two hours by car from Qazvin, which makes it a half-day or full-day excursion rather than a city stop. It is a change of scene from the dry, cold climate of the Qazvin plain.
Combine it with a mountain day if you are already heading out towards the Alborz, and check conditions locally before committing to the swim.
If you only have one day
Morning. Start at the Jameh Mosque of Qazvin while the courtyard is still cool, then walk to the Al-Nabi Mosque. Continue into the bazaars and let yourself get slightly lost before surfacing at the Sa'd al-Saltaneh Caravanserai.
Afternoon. Take a break at Negarossaltaneh Café on Rasteh Vazeer in the Sad-o-saltaneh complex, then visit the Qazvin Museum for context. Walk Sepah Street, the first street built in Iran, and finish the afternoon at the Ali Qapu mansion and its museum.
Evening. Return to the bazaar area to buy confectionery, then, if you want a local evening out, watch an Iranian film at Bahman Cinema in front of Melat Park. Save Alamut Castle and Ovan Lake for a second day, since both need a car and most of a day.
Frequently asked questions
Is Qazvin worth visiting if I am based in Tehran?
Yes, if you want a historic provincial capital within reach of the mountains. Qazvin is about 150 km northwest of Tehran, and from the city you can make a day trip into the Alborz to Alamut Castle.
How do I get to Alamut Castle?
You go from Qazvin into the mountains of Alborz as a day trip. The castle was reconstructed around 2013 and is a UNESCO World Heritage Site, and the surrounding area is used for hiking and trekking.
What is Qazvin known for?
It was a capital of the Safavid Empire for over forty years, from 1555 to 1598, and is known today as the calligraphy capital of Iran. It is also known for its traditional confectioneries, such as Baghlava, and for its carpet patterns.
Can I visit the mountains without a car?
The sources describe Alamut and the paragliding sites at Shafi Abad and Barajin Road as things you arrange locally, for example through a local agent such as Irantaste. Ovan Lake is about two hours by car from Qazvin.
Start by fixing your dates and deciding whether Qazvin is your base for the Alamut valley or a stop on the road between Tehran and the Caspian, then build the walking day around the bazaar and the mosques.
