In honour of the royal visit, he British Ambassador hosted a Queen's Birthday Party.
It's been an eventful day, and one which saw William and Kate arrive in Warsaw with George and Charlotte before moving on to the presidential palace and carrying out several engagements focused on exploring Poland's history and supporting young entrepreneurs.
The Duke and Duchess were greeted the President and First Lady.

The Duke and Duchess with the British Ambassador to London Jonathan Knott (in the grey suit), their host for the evening. Speaking to Sky News about the tour Mr Knott said: "I think what the visit is really going to do is accelerate that process of deepening our relationships and making sure that as we go through the process of leaving the EU our relationship doesn't weaken - actually it gets stronger."
William and Kate mingled with guests.
The couple were all smiles and appeared to very much enjoy their time chatting.
An overview of the party.
The Orangery was built by Adam Adolf Loewe and Józef Orłowski in 1860. Neo-classicist with eclectic elements, it was designed to shelter the collection of orange trees. The building was necessary because Tsar Alexander II of Russia, who purchased one of the largest European collections of tropical plants from Nieborów, could not transport it to Saint Petersburg due to climate conditions there. The collection's pride were the long-lived orange trees, 124 of them in total. Unfortunately, during World War I, they were left without appropriate care and froze. The building consists of an oblong hall, with glass walls. Today it houses a tropical garden and a restaurant in the northern wing.
Prince William gave a speech in front of 600 guests.
During the speech William said: "Tonight we have double reason to celebrate: we mark the birthday of my grandmother the Queen, and we celebrate the depth and breadth of the shared ties of our two great countries. The links between Britain and Poland go back centuries, and are steeped in a rich history of cultural exchange and close commercial relations. The Shakespeare Theatre in Gdansk, which Catherine and I will see tomorrow, is a reminder that cultural links have long been at the heart of our close relationship. Shakespeare's plays were performed in Poland – and indeed in Polish – very soon after they were first staged in London. Around the same time, grain merchants from Poland were plying their trade into Britain, pathfinders for the many entrepreneurs and skilled workers who make the same journey in both directions today. We in the United Kingdom value our links with Poland enormously. We admire Poland as a remarkable example of courage, fortitude and resilience. You have survived centuries of assaults on your land, including partitions that were designed to wipe you off the map of Europe. Catherine and I were very moved to visit the Warsaw Rising Museum this afternoon with President and Mrs Duda; as I know we will be, too, when we visit Stutthof concentration camp tomorrow, a reminder of the suffering of Poland's people and of the Holocaust."
William added: "Catherine and I are delighted to be embarking on our first visit to Poland, and we hope to return many times in the years to come. Mr President and Mrs Duda, thank you for your hospitality, and thank you to everyone for the warm welcome you have given us, which underlines the strength of the relationship between our two peoples."
Prince William concluded with a message from the Queen:
'Prince Philip and I send our warmest good wishes to all of you attending this special Garden Party on the occasion of The Duke and Duchess of Cambridge's first official visit to Poland. We have fond memories of our visit to Poland in 1996, when we experienced its world-renowned hospitality in Warsaw and Krakow. I am delighted that The Duke and Duchess of Cambridge will be able to experience this for themselves in Warsaw and Gdansk.
In 1996, I spoke about the depth of British-Polish relations, dating back nearly a thousand years, and it gives me great pleasure that the friendship between our two nations and peoples has since gone from strength to strength. I have no doubt it will continue to prosper in the years to come.
'I hope you have a most enjoyable and memorable evening. Dziękujemy i miłego wieczoru.'

A glass of wine to end the day.
Kate's dress is by Polish designer Gosia Baczynska.
The Duchess tends to wear at least one piece by a local designer when touring another country and tonight's reception seemed the perfect time to choose a Polish design. The dress is really quite a departure from Kate's signature; it's a contemporary piece but also quite edgy for the Duchess. The black and white dress features a plunging neckline and leaf embellishment at the waist. Jagoda from What Kate Wore FB found a product shot of the dress.
Ms Baczynska was the first Polish designer to feature in the Paris fashion week calendar. She is known for creating bold and daring designs. What Kate Wore noted the designer was actually at the party tonight. On her Facebook Page Gosia wrote "It is an honour and privilege that Princess Kate has worn our custom made cocktail dress".
More on the look from The Telegraph:
'Aside from its diplomatic message, the dress is a bold choice from the Duchess who has shown greater willingness to experiment with her style over the past year. The jagged, black-edge pleats on the bottom part of the dress offer a playful contrast to the delicate floral black applique at the waist while the deep v-neckline frames her pearl necklace- debuted during a visit to Paris in March- elegantly.
Although Baczynska is now well-and-truly Warsaw based and a go-to designer for many of Poland's wealthiest and most famous women, she does have ties to London. Her biography reveals that she gave up studying Fine Arts to move to London in 1991. She then spent time working for a seamstress and honing her dressmaking skills in the city before returning to her hometown of Wroclaw to begin her business.
Baczynska- who also recently dressed Halle Berry in a silver sequinned mini dress- describes how her fashion ethos is a "a revolt against the greyness that surrounded me" in the post-Soviet era. It will surely have impressed the Duchess that Baczynska began her business with very little funding, finding success through hard work and good reputation.'
Kate's choice of jewellery and shoes for a black McQueen dress for a reception in Paris in March served as inspiration for the completion of tonight's look.
Kate wore her very chic Gianvito Rossi Ankle Strap Suede d'Orsay Pumps. The $775 pumps are described: "These Gianvito Rossi pumps demonstrate traditional Italian craftsmanship and designs in a d’Orsay silhouette. Softly structured from black suede, the pointed-toe pair is finished with a buckle ankle strap for a slender sculpt." They remain available in very limited sizing at Barneys.
Kate's also wearing the same statement pearl necklace with four large pearls.
And Balenciaga earrings.
Kate completed the look with her black Prada clutch.
Kate's hair was styled in a gorgeous updo.
