Castelul Pelisor a fost deschis publicului vizitator in februarie 1993. Muzeul, cu o valoare inestimabila, ce cuprinde o valenta istorica, o alta memorialistica si una artistica, constituie o importanta componenta a zestrei culturale a poporului roman. Acest edificiu este parte integranta a vastului ansamblu arhitectonic creat de regele Carol I pe valea paraului Peles, intr-o perioada ce se suprapune practic intregii sale vieti traita in Romania. In paralel cu castelul Peles, au fost construite in apropiere Casa Cavalerilor, Economatul, Casa Corpului de Garda, Casa Arhitectilor, Casa Gradinii, iar mai tarziu, intre 1899 – 1902, Castelul Pelisor, un dar oferit de regele Carol I principilor moştenitori. Arhitectul şef al castelului Pelisor, Karel Liman, respecta cerintele comanditarului pentru arhitectura exterioara, cu elemente "Half-timbered" but also adding Romanian elements, which give the building a cheerful touch: the two towers covered with colored sandstone tiles, like the church steeples in Bucovina. Regarding the interior architecture, K. Liman used, undoubtedly at the request of Princess Maria, along with elements of "Art 1900", Romanian elements: specific niches of the Prahova Valley, the division of space by using Brancovan elements, the amplification of functionality by dividing the space horizontally. Because, through the gradual understanding of the nature of the Romanian people, with whom she came to identify like no other royal personage, Maria understood the necessity of including the function  "national" in resedinta regala. Decoratia interioara, conceputa de Maria in diverse perioade, 1902 – 1903 si 1925 – 1928, ilustra crezul ei in materie de frumos. In testamentul moral adresat "To the Romanian Country and People"The queen confessed:  "If all beautiful things remind you of me, I will be fully rewarded for the love I have borne you, because for me beauty was a creed." Maria's daring artistic endeavors did not have, like Carol I, civilizing or exemplary claims; they were the manifestation of her nonconformist spirit, open to the new, desiring freedom. Like the Cotroceni Palace, the Pelisor Palace will experience several stages of decoration, which will illustrate the evolution of Queen Maria's feelings and taste. From "the golden nests", where the crown princess, wounded by the real world, could take refuge to dream away from the cruel reality, to the severe purification of lines, to the geometricism of the Modern Style or to the inclusion of elements of Romanian art in her personal style, artistic expression of the Queen's identification with the pains and joys of the Romanian nation. This is the reply that"Queen of all Romanians" a dat-o, peste ani, regelui Carol I si germanitatii sale nezdruncinate. Castelul Pelisor dezvaluie, prin decoratia sa interioara, personalitatea romantica, misterioasa, indrazneata, promotoare a unei arte noi si insolite a reginei Maria, caci, stilul ales de ea pentru aceasta "dream house" is "Art 1900".
