The collection is generally arranged according to 6 broad subject themes: The
Bible and Saints, Mythology and Allegory, Portraits and Self-portraits, Still Life and Landscape, Mother and Child and Impressionism. It is displayed in 8 rooms and the interlinking hallways. This is the main arrangement by room:
THE IMPRESSIONIST ROOM in which one can find the portrait of Renoir's son, Pierre.
Amongst the works of many other artists in this room, one finds works by Goya, Fantin-Latour, van Gogh, de Chirico and Dufy.
THE MYTHOLOGY AND ALLEGORY ROOM with, for example, a painting by one of the most famous exponents of Academism, William Adolphe Bougereau, showing Venus and Cu-pid and entitled „Spring" and a work by Giovanni Antonio Pellegrini on the theme of Hercules and Omphale (the last of the Twelve Labours of Hercules).
In THE ROTUNDA there are over 80 portraits and self-portraits, including the self-portraits of Murillo and Kneller, and portraits of kings, aristocrats and dignitaries, as well as many portraits of less renowned people. There is also an extraordinarily compelling Polish work in the outstanding portrait by Jan Boleslaw Czedekowski entitled „Letter from Home - the Artist`s Wife and Daughter".
In THE MOTHERHOOD-MOTHER AND CHILD ROOM one finds delightful paintings depicting Motherhood, such as that of John William Haynes, or two portraits of famillies, namely Nicholas Maes' „Sykes Family" and Jan Weenix's „Mother with Children on the Terrace".
In THE MARIAN ROOM paintings depicting the Blessed Virgin Mary and child predominate; they range in style from altarpieces to quite small, extremely informal works.
In THE BIBLE ROOM are works showing both Biblical episodes and events from the lives of the Saints. Fine examples are Jacopo Robusti Tintoretto's „David Receiving News of the Death of Uriah", Andrea Meldolla lo Schiavone's „Deposition", and David Tenier the Younger's „Ecstasy of St. Francis".
THE STILL-LIFE AND LANDSCAPE HALLWAY and the gallery above the Rotunda where the eye is caught by a lovely, colourful pinting of «Hollyhocks» in a Japanes vase, the work of the Frenchman Georqes-Jules-Ernest Binet as well as by „Still Life with Fruit" with a Caravaggio-like use of light and shade, painted by the Neapolitan Giovanni Battista Ruopolo.
THE GERSON ROOM in which a notable role is played by the famous painting by Wojciech Gerson, entitled „The Baptism of Lithuania"; the room also houses some of the collections` still life paintings.
The oldest painting in the collection, from the School of the Marches (Italian), dates from the mid 14th Century; the most recent dates from the century just ended.
A number of female artists are represented. This method of grouping the paintings brings some sense of order to the display but it does not permit a comparative study of the works of individual artists. Thus, the lovely paintings of Zuber-Buhler must be sought in the rooms housing „Mythology and Allegory” as well as the “Gerson Room” and “Mother and Child” The paintings of one of the world`s most famous female artists, Angelika Kauffman, can be found in the Marian Room and in the hallway between the Rotunda and „Mother and Child". The majority of the paintings and sculptures emanate from Italian, Dutch, Spanish and British artists. They include, amongst others, works by masters, or their followers, such as Durer, Cranach the Older and the Younger, Titian, Pontormo, Carracci, Caravaggio, Reni, Rubens, Albani, Ribera, Jordaens, Poussin, Van Dyck, Velazquez, Rembrandt, da Cortona, Ruisdael, van Es, van Schooten, Nattier, Boucher, Greuze, Reynolds, Gainsborough, Leighton, Lawrence, Constable, Diaz de la Pena, Sisley Corot, Sorolla y Bastida, Vlaminck, van Rysselberghe, Wilson Steer and other Impressionists.
