Two 18th century shipwrecks have been found laden with bottles and ceramics at the bottom of the sea.
Both wrecks were discovered accidentally.
Divers were investigating reports of a WWII Nazi U-boat wreck in the Baltic Sea in May.

But they instead found a 300-year-old wooden shipwreck with its cargo still intact.
The following day, the Polish divers found another sunken steamer just over a mile away.
They were found just three miles off the Hel Peninsula in northern Poland.
Both wrecks were resting on the seabed at a depth of between 197ft to 230ft.
A spokesperson for the maritime exploration company Baltictech said: “Just two kilometres apart, we found two well-preserved wooden wrecks.”
The ships were stocked with bottles and pottery that were taken away for analysis.
Researchers determined that some of the ceramics on the first ship originated from the mountainous region of Westerwald in western Germany between 1725 and 1740.
Baltictech said: “So, we have a wooden ship from the mid-18th century.”
They added that the second ship is believed to have been built towards the end of the 18th century.
However, further explorations may prove difficult due to the wrecks’ resting place on a waterway.
The dive company explained: “It’s a shame that they lie right on the waterway (between Gdańsk and Gdynia) and will probably lie there quietly for decades to come.”
They added: “We also came across a well-preserved plane wheel, which definitely should not have been there.
“We will probably never solve that particular mystery.”
Baltictech hit the headlines in July last year when they discovered a shipwreck about 20 nautical miles south of the Swedish island of Öland.
The wreck contained hundreds of bottles of fancy champagne and mineral water produced by Selters, a German brand that still exists today.
Baltictech lead diver Tomasz Stachura told Need To Know: “We encountered a 19th century sailing ship in very good condition, loaded to the sides with champagne, wine, mineral water and porcelain.
“We saw more than 100 bottles of champagne and baskets of mineral water in clay bottles.
The clay bottles helped them date the wreck to between 1850 and 1867.
Stachura believes the cargo was making its way to the Russian Tsar Nicholas I, who reportedly lost a ship in the region in 1852.
He explained: “That would explain why the ship had this cargo – which was all very exclusive.
“In those days, mineral water was treated almost like a medicine and only went on royal tables.”
