"Rauberji, staro kranjsko plemstvo, so prišli v posest Krumperk v prvem desetletju 16. stoletja. Krumperk pa takrat kajpak še ni bil takšen, kot je dandanašnji. Bil je le manjši dvor z imenjem, ki je imel tipično obliko srednjeveških dvorov - obliko stolpa in se zato tudi virih omenja le kot stolp. Kot Turn Chrawperg ga označuje najstarejši ohranjeni vir iz leta 1410, še prej pa se po Valvasorju imenuje Thurn unter Kreutberg ali Thurn zu Kreutberg. Predloga pod in torej označujeta stolpasto stavbo ob neki drugi, pač večji in bolj znani grajski stavbi, kot jo poznamo, denimo, s Keblja na Pohorju, je stala v bližini enako imenovanega gradu. Gre pri Kreutber Chrawpergu za danes razvaljeni grad Koprivnik blizu Moravč, ki prvotnega nemškega imena ne poznamo? Morda, in če, potlej daleč misel, da je današnja grašcina Krumperk njen pravni naslednik.
Graščino Krumperk, ki je skoraj nespremenjena pričakala cas, je okoli 1580 pozidal zmagovalec v bitki pri Sisku Ad Rauber. Bila je grajena po tistih dob novih, italijanskih načelih ravninskih dvorcev, kakršni so se pri nas že nekoliko prej uveljavili z grašcinama Brdo pri Kranju in Brdu pri Lukovici (Sumi). Njih značilnost je štirikotna zasnova, kjer štirje približno enako veliki trakti obdajajo kvadratno, arkadirano notranje dvorišče, na zunaj se uveljavljajo kot kombinacija utrdbe in dvorca. Utrdbeni značaj se kaže predvsem v pravokotnih vogalnih stolpih, ki so višinsko izenačeni s stavbnimi krili, obenem pa jih obteka obrambni konzolni venec, sloneč na podvojenih konzolah ter opremljen s strelnicami in izlivnicami za smolo - ta se potem nadaljuje tudi vrh stanovanjskih traktov, tako da učinkuje na stavbi kot nekakšen dekorativni friz. Vse drugačna pa je stavba, če jo doživljamo z dvorišča. Tu ni nicesar trdega, trdnjavskega več. Utilitarno strogost srednjeveških grajskih dvorišč so tu zamenjali mehki loki arkad, ki ustvarjajo vzdušje udobja in razkošja. Res, kot bi se znašli nekje sredi sončne Italije; kjer se ni bati nobenega sovražnika. Ima pa krumperška graščina neko posebnost. Enonadstropne arkade, ki jih opirajo vitki toskanski stebriči, so v pritličju dvakrat širše kot v nadstropju. Obtekajo tri strani dvorišča, arkadni hodniki pa imajo v pritličju še običajne križne oboke, medtem ko so oboki v nadstropju okrašeni s sistemom mrežastih grebenov - daljnim in hudo poenostavljenim odmevom slogovno preživelih gotskih reber. A kljub temu - renesansa je tu zadihala iz polnih pljuč. Še gotsko, na ajdovo zrno prirezana kletna okenca se zde ob drugih, že renesančno oblikovanih stavbnih členih le še zanemarljiva nadrobnost, ki jo komaj opazimo in ki še daleč ne moti renesančno uglašenega razpoloženja celote. Isto velja za kamniti vhod v klet, ki ima še gotsko posnet profil, a lok se je že polkrožno usločil in tako ostaja vse skupaj le še medel spomin na neko slogovno hotenje, ki se je že zdavnaj preživelo. Nasproti grajskega vhoda so v barocni dobi pozidali samostojno stoječo kapelo. Njena nekdanja kvalitetna oprema je šla tako kot ostali grajski inventar po zadnji vojni v vse vetrove."

"Rauberji, old Carniolan nobility, came into possession Krumperk in the first decade of the 16th century. Krumperk then of course it has not been as good as it is today. He was a small court with imenjem, who had a typical form of medieval manors - the form of a tower and therefore the source is mentioned as a tower. Chrawperg Turn As indicated by the oldest preserved source in 1410, having previously appointed after Valvasor Thurn Thurn unter Kreutberg or u Kreutberg. The template below and then indicate the tower building on another, but more and most famous castle building, as we know, for example, by Keblja on Pohorje, stood near the castle the same name. Kreutber is in ruins today Chrawpergu for Castle Koprivnik Moravce close to the original German names are not known? Perhaps, and if, then far the idea that today's mansion Krumperk his successor.Krumperk mansion, which is almost constant waiting time is about 1580 built a winner in the battle of Sisak Ad Rauber. It was built after those periods of new principles of Italian flat mansions, such as with us a little earlier by means of the mansion and at Brdo Brdo pri Lukovici (Sumi). They feature a quad design, where approximately equal to four more tracts surrounding the square, arkadirano inner courtyard, the outside is increasingly recognized as a combination of fortress and castle. Fortification character is seen primarily in rectangular corner towers, which are equal elevation of building wings, while the cornice brackets defensive turnaround times, leaning on duplicate consoles and is equipped with a shooting for resin - which is then continued top housing tracts, so that effect on the building like a decorative frieze. All but the building is different, if we are experiencing from the courtyard. There is nothing hard, the fortress anymore. Utilitarian rigor medieval castle courtyard there are soft-switched arcade arches, which create an atmosphere of comfort and luxury. I really like to find somewhere in the middle of sunny Italy, where no fear no enemy. Krumperška has a peculiar mansion. Two-story arcades by slender Tuscan columns are based, are twice as wide as the ground floor level. Obtekajo three side of the courtyard, arcaded corridors on the ground floor have the traditional cross-vaults, while the arches on the first floor, featuring a grid system of reefs - distant and severe simplified anechoic chamber surviving Gothic style ribs. And yet - Renaissance is here in full-lung breathing. Even the Gothic, the buckwheat grain is truncated basement windows may consider the other, has created a Renaissance building articles only insignificant detail, you barely see that far and do not mind the whole mood of the Renaissance tuned. The same applies to the stone entrance to the basement that has a gothic profile shot, but the bow was already semi-circular arched and everything remains only a faint memory of a stylish desire, which has long survived. Opposite the castle entrance in the Baroque period built a chapel standing alone. Her former quality equipment is gone like the rest of the castle inventory after the last war in all winds. "
