Everything stolen - shop to replace ?

I'm very sorry to hear that. If you are in central Cologne there is an abundance of shops there. Especially on and around Hohe Straße, you'll probably find everything you need there.

How awful for you. I hope you've already filed a police report so you can make a claim on your travel insurance.

My go to for dept. stores in Germany would be one of the Galerias. I think there's both a G Kaufhof and a G Karstadt in Cologne. If you go to Google maps for cologne and select department stores, a lot more options should pop up.

So sorry to hear of your travel trouble. In addition to the department stores CJean mentions in the city center, there should be a pharmacy and shoe store with a block. German towns are very well layed out and shoppable.

EDIT: also file a police report and keep all receipts. Your travel, cc or other insurance may reimburse you but check your options.

I am sorry to hear that.

To existing information given I like to add that Cologne has a real good second hand clothing scene. Several shops in the city, also some kind of a department store for this (Humana).

I guess you informed police and rental car company already.

How truly terrible!!! This happened to us.

Were things visible in your car? Or was everything in the trunk?

This is one of several reasons why I no longer rent vehicles in Europe, and in particular when I did do it back in the day, I never left any belongings or luggage in a rental vehicle while I was enroute from one hotel to another, stopping on the way at any tourist site. Anytime I parked a rental at a tourist site, I had already left all of our stuff at a hotel, I never left anything in the car that could be stolen and screw up our trip.

I learned this lesson In Normandy where all of the parking lots at the various historical sites have warning signs about car break-ins and thefts. In Europe it seems there are literally no rental vehicles with a locking trunk (or even if you reserve one, or thought you did, you are really only reserving a vehicle class and will only get what they have on the lot). Literally every rental is hatchback, or sometimes an SUV or minivan, and all of your stuff is easily seen from outside the car by would-be thieves. Even with a locking trunk, while I think it is a little safer, the mere fact you are parking your rental at a tourist site marks you as a target, and trunks are easily defeated by thieves.

I know you don't want to hear it, but what happened to you is quite common over there. My advice is more for others who read this thread.

Be very careful in Italy, it doesn't get any safer there...

I am terribly sorry this has happened to you. What an awful feeling.

I hope the shops that people have suggested will work out for you to get enough things to get you through the trip.

I've found the Rossman's chain to have toiletry type items when I've needed them.

BTW Galeria Kaufhof and Karstadt have combined. It is a good choice for pretty much everything.

"dm" and Müller's are good for toiletries.

Clothing stores: H&M, C&A and TKMax

My wife is the shopper.

I hope the OP will come back and let us know how they made out.

You should be able to buy everything you need at Peek and Cloppenburg department store.
