Around 28,000 visitors came to Callendar House in 2006, up over 50% on the previous year. This may be in connection with the recent local attraction, The [[Falkirk Wheel]], whose visitor numbers doubled during the same period. Callendar House is being developed as a major heritage centre. The house interiors have since been restored to their former [[Georgian architecture|Georgian style]] glory. It is the principal museum in Falkirk district, as an [[art museum|art]], [[history museum|history]], and [[historic house museum]]. It has two magnificent reception rooms, the Pink Room (the Drawing Room) and the Green Room (the Morning Room), as well as a fully working [[Georgian period in British history|Georgian period]] kitchen, dominated by a huge open fire, offering visitors the opportunity to step back into a world that has now gone. Staff in period costumes give insights into working conditions in the house over the centuries and prepare the same food that was enjoyed at the grand social occasions that once took place there. Permanent exhibitions include "William Forbes' Falkirk" and "The Antonine Wall". The other galleries show around seven different exhibitions a year from all around the world. There is also a history research centre, where all of Falkirk's historical archives are kept, housed in the Victorian oak-panelled library. [[File:The Wall - geograph.org.uk - 282048.jpg|thumb|left|The [[Antonine Wall]] passes through the park]] The grounds of the house contain a pitch and putt course, crazy golf, a children's adventure playground (with the largest slide in Scotland), a boating lake and the [[Antonine Wall]]. There is also a contemporary art gallery, the Park Gallery, which has been relocated into Callendar House itself. Callendar Estate extends to and is open for walks through the woodland and also home to the Forbes family mausoleum, a large domed circular Grecian-Doric building which contains the remains of many of the Forbeses. Various events are held in the grounds throughout the year, including the annual firework display, which is regularly attended by over 70,000 people, as well as the national street arts festival, [[Big in Falkirk]], the largest round of the Scottish Cyclocross Series and the Scottish National Cross Country Championships. Behind the house lies Callander Wood, which contains a number of pre-determined paths popular with ramblers and dog walkers.
